Pavel Yaskevich dde9fa35e8 [ConstraintSystem] Re-activate constraints if, due to incorrect reference, member type has been bound before base type ...

If member has been bound before the base and the base was
incorrect at that (e.g. fallback to default `Any` type),
then we need to re-activate all of the constraints
associated with this member reference otherwise some of
the constraints could be left unchecked in inactive state.

This is especially important for key path expressions because
`key path` constraint can't be retired until all components
are simplified.
