MethodReturnCheck should detect not-thrown exceptions returned by factory methods

[fiveOO]

MethodReturnCheck(RV_EXCEPTION_NOT_THROWN) detects not-thrown exceptions created by calling a constructor directly.

It would be helpful to detect not-thrown exceptions returned by a factory method in addition.

// is detected
new IllegalArgumentException("x must be nonnegative");

// should be detected
MyException.someLogicWentWrong("value1", "value2");
