this logic is duplicated between here and getContextualSignature. consider refactoring it.

done, although it still does the work twice in the case that there is no contextualSignature.
1. Remove intersection code. The any-defaulting code means that it's never hit. 2. Remove some code duplication.
If a contextual signature is found, if its thisType is undefined, then the contextual type of `this` is now `any`. Previously `checkThisExpression` would keep looking for a different type for `this`. Also update tests to show this new behaviour.

OK, I changed the behaviour of contextual signatures that don't define @mhegazy I think this is a good compromise. Can you take a look? |
