Fix #4123 issue about "False positive on Enum.__members__.items()". I add a conditional at _emit_no_member function in typecheck.py.

Thank you for this fix, we're going to cherry-pick it to 2.7.2, could you rebase and add a quick summary in What's New in Pylint 2.7.2? in Changelog, please ?

[ikraduya]

Sure, maybe I could also add __members__.values and __members__.keys as well?
As stated from this #4123 (comment)

+1, closing two bugs with one MR is always nice :D

[Pierre-Sassoulas]

Thank you for the update @ikraduya , I'll merge as soon as pre-commit is fixed.

Could you rebase this branch onto the current master and force push it?
That would take care of some duplicate commits.

@ikraduya we have a deadline sunday 28 at 8pm (tomorrow) for the release of 2.7.2 if we want this to be in the next debian :)

I squashed everything and used the fix by @cdce8p, it's all good. Thank you for the fix !
