project: Check if dotgit exists w/out symlink check

Browse Source 
os.path.exists returns false on a broken symlink. This is not what repo
needs when checking if a project is setup properly.

For example, if src/foo/.git can't be resolved, repo tries to create
symlink and that results in FileExistsError.

Use lexists which returns True even if symlink is broken. That will
force path where repo checks where symlink is pointing to and will fix
it to the correct location.
