Windows symlink broken by Path().resolve() #5905
Description
On Windows 10 (v1903, 18362.356) I have created a D: drive using Subst. My tests used to work, but I recently upgraded pytest and found that I now get this error message for every test file:
____________________________________________ ERROR collecting test_feature_toggles.py _____________________________________________
import file mismatch:
imported module 'tests.unit.test_feature_toggles' has this __file__ attribute:
D:\development\psma\api\api-master\api_services\pav\imp\src\tests\unit\test_feature_toggles.py
which is not the same as the test file we want to collect:
C:\d_drive\development\psma\api\api-master\api_services\pav\imp\src\tests\unit\test_feature_toggles.py
HINT: remove __pycache__ / .pyc files and/or use a unique basename for your test file modules
Well, they are the same file, deleting ALL pycache/.pyc files has no impact and I believe the problem was introduced in this PR:
#5564
I believe this may be the same cause of a different bug: #5826
Is it possible to use Path().absolute() instead?

To recreate, use subst to map a folder where you have tests into a new drive letter, cd to that folder on the new drive letter and try to run the tests again.
