GH-328: Fix RecoverAnnRH return types matching

Fixes #328

The loop in the `RecoverAnnotationRecoveryHandler.isParameterizedTypeAssignable`
only checks the first type argument of the `ParameterizedType` and returned.
When there are two type arguments, the result will be wrong.

* Fix `RecoverAnnotationRecoveryHandler.isParameterizedTypeAssignable` to continue matching
for next generic arguments
