Giving invalid content type without "application/" should give "415 Invalid Content Type" not an NPE error

PUT /api/space/tag-management/tags/<id>/targets (This is our internal API) with a content type of:

vnd.net.juniper.space.target-management.targets+xml;version=1;charset=UTF-8 (note missing application/ in Content-Type)

This method gives a 500 (NPE) error, instead of the Invalid Content Type or Method not Allowed error.
