Actual and Expected are being mixed up in assert diffs

[abotalov]

Currently the verbose diff looks like:

def test_function():
  assert 3 == 4

4 != 3

Expected :3
Actual   :4
 <Click to see difference>

def test_function():
>     assert 3 == 4
E     assert 3 == 4

../../test_sample.py:4: AssertionError

As the usual idiom is assert actual == expected, these words are mixed up.

Similar to #3333.

I think you are copying pasting the output from PyCharm, right? In that case that's PyCharm producing that output, and pytest really cannot do anything about it.

Yes, I copy pasted it from PyCharm, thought it's generated by Pytest.
