Remove createESLintConfig option from tests/helpers/acceptance.

This option was added at a time where the default ember-cli blueprint
did not include any eslint config (it was housed in ember-cli-eslint
itself and only added during `ember new` by running the
`ember-cli-eslint` blueprint). At that time a basic ESLint config was
needed to prevent tests from completely blowing up, so this option was
added...

Fast-forward to the present: the default eslint configuration is now
managed by ember-cli itself, and this override option is not providing
value (in fact it is adding pain because it does not confirm the default
blueprint passes linting).

This commit removes the now unneeded feature...
