3241fc3103 Don't fail if hasattr fails when rewriting assertions 
When rewriting assertions, pytest makes a call to
`__name__` on each object in a comparision. If one of
the objects has reimplemented `__getattr__`, they could
fail trying to fetch `__name__` with an error other than
`AttributeError`, which is what `hasattr` catches.

In this case, the stack trace for the failed `__getattr__`
call will show up in the pytest output, even though
it isn't related to the test failing.

This change fixes that by catching exceptions
that `hasattr` throws.

e1e4b226c6 👌 Address code review 
Edited the changelog for extra clarity, and to fire off auto-formatting

Oddly enough, keeping `filename='{filename!r}'` caused an error while
collecting tests, but getting rid of the single ticks fixed it
Hopefully closes #3191

37d2469266 Use a PurePath instance to do matching against patterns in assertion rewrite 
This way we don't need to have real file system path, which prevents the
original #3973 bug.

1df6d28080 Fix assertion rewriter crash if cwd changes mid-testing 
Unfortunately we need to get a `py.path.local` object to perform the fnmatch
operation, it is different from the standard `fnmatch` module because it
implements its own custom logic. So we need to use `py.path` to perform
the fnmatch for backward compatibility reasons.

Ideally we should be able to use a "pure path" in `pathlib` terms (a path
not bound to the file system), but we don't have those in pylib.

82a7ca9615 Avoid possible infinite recursion when writing pyc files in assert rewrite 
What happens is that atomic_write on Python 2.7 on Windows will try
to convert the paths to unicode, but this triggers the import of
the encoding module for the file system codec, which in turn triggers
the rewrite, which in turn again tries to import the module, and so on.

This short-circuits the cases where we try to import another file when
writing a pyc file; I don't expect this to affect anything because
the only modules that could be affected are those imported by
atomic_writes.
