no-member messages for M2M filter and *_set attributes

[talkingtoaj]

I erroneously receive the following pylint no-member error messages:

Instance of 'ManyToManyField' has no 'filter' memberpylint(no-member)

• Seems to think filter methods don't work on ManyToMany fields

Instance of 'Tip' has no 'tipencounter_set' memberpylint(no-member)

• Seems unable to determine that the other end of a One-to-Many relationship has a _set attribute.
