fake_pathlib's resolve() does not reproduce error when path has file ancestor

[romanlevin]

Under Python 3.6:

>>> p = pathlib.Path('/path/to/file/this can not exist')
>>> p.resolve()
Traceback (most recent call last):
  ...
NotADirectoryError: [Errno 20] Not a directory: '/path/to/file/this can not exist'

pyfakefs.fake_pathlib.FakePath.resolve() does not raise an exception.

Thanks for the report - you may be the first user of fake_pathlib so far, so we are certainly happy to get any feedback. I will have a look into this.

I just added some fixes - please check if this solves your problem.
Note that you have to use the latest Python 3.6 beta (beta 4), as resolve() has got an additional strict argument, and the default behavior has changed (e.g. it does not throw with your example code).

@mrbean-bremen Thanks for pointing out this change in 3.6.0b4. It's not very well documented and would have taken me a while to find otherwise.

[romanlevin]

Verified that issue is solved on Python 3.6.0b4 with e3449bf.

[mrbean-bremen]

Well, we have to check again after the final version gets out - there always may be some changes. Though I don't really expect any, as the final version shall be out in another 2 weeks.

[romanlevin]

Yeah. although I wouldn't have expected this kind of compatibility-breaking change between beta releases, either.
