Fixed a NPE in AssumeThatInsteadOfReturn inspection quickfix for empty else branches.

Fixed missing description for AssumeThatInsteadOfReturn inspection. Added new AssertThatCollectionOrMapExpression inspection that tries to pull out methods such as isEmpty() or contains() out of an actual assertThat() expression. Added more method calls that are considered extension points.
