[issue13387] add exact_type argument to assertIsInstance

[Éric Araujo]

Éric Araujo <merwok at netwok.org> added the comment:

I find that assertIs(type(x), someclass) is very clear, whereas an assertIsInstance that would not behave like isinstance depending on one argument would be non-obvious to me.
