With this fix header "Content-Type: application/json; charset=utf-8" working same as "Content-Type: application/json" for parse input data
* Fix code style, add $consumes length check.
* Add isContentTypeAllowed static method and tests
* Fix old tests
Right now serializer doesn't support anything beside json and xml.
Call tests with application/json instead of form data.
