fix: RecursiveTypeMapper returns exception which can't be handled by StandardServer (#646)

* fix: RecursiveTypeMapper returns exception which can't be handled by StandardServer

RecursiveTypeMapper throws CannotMapTypeException when fails to find class by name. This exception goes through the GraphQl executor instead of catching and wrapping into ExecutionResult. Non wrapped exception does not trigger HttpCodeDecider.
Schema test trust more to input than configuration which is not optimal, great possibility to improve configuration validation.

Fixes: #336

* feat: new special Exception class when request type unknown

Fixes: #336

* fix: move asserts

Fixes: #336

* polish changes

Fixes: #336
