Error raised by version 5.2.1+ when repo contains symlinks

[andreipetre]

I came across an issue introduced by version 5.2.1 where it would raise an error for a repo with symlinks to Python packages.

Traceback (most recent call last):
  File ".../bin/isort", line 8, in <module>
    sys.exit(main())
  File ".../isort/main.py", line 829, in main
    for sort_attempt in attempt_iterator:
  File ".../isort/main.py", line 818, in <genexpr>
    sort_imports(  # type: ignore
  File ".../isort/main.py", line 125, in iter_source_code
    dirnames.remove(dirname)
ValueError: list.remove(x): x not in list

isort 5.2.0 runs fine on the repo, 5.2.1 raises the above error. All versions after 5.2.0 (including 5.4.2) raise the same error.

This is already fixed on the develop branch (acd14d8).

A fix for this issue has just been deployed to PyPI in version 5.5.0 of isort.

Thanks!
