 #KT-1890 fixed

Fixed problem when JetTypeElement was replaced by JetTypeReference, resulting in invalid PSI structure.

Specify type explicitly quick fix now has lower case of letters (due to naming convention of quick fixes)

Changed RemovePartsFromPropertyFix so it uses SpecifyTypeExplicitlyAction.addTypeAnnotation() instead of AddReturnTypeFix.addPropertyType().

Moved addTypeAnnotation/removeTypeAnnotation methods from refactoring package to SpecifyTypeExplicitlyAction.

MUST_BE_WRAPPED_IN_A_REF was renamed to CAPTURED_IN_CLOSURE (immutable variables are stored there as well)
