Bump pytest from 5.3.5 to 5.4.0

[dependabot-preview]

Bumps pytest from 5.3.5 to 5.4.0.

Release notes

Sourced from pytest's releases.

pytest 5.4.0 (2020-03-12)

Breaking Changes

• #6316: Matching of -k EXPRESSION to test names is now case-insensitive.

• #6443: Plugins specified with -p are now loaded after internal plugins, which results in their hooks being called before the internal ones.

  This makes the -p behavior consistent with PYTEST_PLUGINS.

• #6637: Removed the long-deprecated pytest_itemstart hook.

  This hook has been marked as deprecated and not been even called by pytest for over 10 years now.

• #6673: Reversed / fix meaning of "+/-" in error diffs. "-" means that sth. expected is missing in the result and "+" means that there are unexpected extras in the result.

• #6737: The cached_result attribute of FixtureDef is now set to None when the result is unavailable, instead of being deleted.

  If your plugin performs checks like hasattr(fixturedef, 'cached_result'), for example in a pytest_fixture_post_finalizer hook implementation, replace it with fixturedef.cached_result is not None. If you del the attribute, set it to None instead.

Deprecations

• #3238: Option --no-print-logs is deprecated and meant to be removed in a future release. If you use --no-print-logs, please try out --show-capture and provide feedback.

  --show-capture command-line option was added in pytest 3.5.0 and allows to specify how to display captured output when tests fail: no, stdout, stderr, log or all (the default).

• #571: Deprecate the unused/broken [pytest_collect_directory]{.title-ref} hook. It was misaligned since the removal of the Directory collector in 2010 and incorrect/unusable as soon as collection was split from test execution.

• #5975: Deprecate using direct constructors for Nodes.

  Instead they are new constructed via Node.from_parent.

  This transitional mechanism enables us to detangle the very intensely entangled Node relationships by enforcing more controlled creation/configruation patterns.

  As part of that session/config are already disallowed parameters and as we work on the details we might need disallow a few more as well.

  Subclasses are expected to use [super().from_parent]{.title-ref} if they intend to expand the creation of [Nodes]{.title-ref}.

• #6779: The TerminalReporter.writer attribute has been deprecated and should no longer be used. This was inadvertently exposed as part of the public API of that plugin and ties it too much

Pytest flipped the plus/minus signs for it's extended diffs,

#6673: Reversed / fix meaning of "+/-" in error diffs. "-" means that sth. expected is missing in the result and "+" means that there are unexpected extras in the result.

so this diff fixes it:

Not at my usual computer else I'd submit a PR.
