Restore support for opening query-based sync Realms with a dynamic schema (#2065) 

* Restore support for opening query-based sync Realms with a dynamic schema

* Adjust how the schema is extended for query-based Realms

* Register constructors for permissions types even no schema is supplied

* Remove some cruft from tests

* Fix a use-after-free in dynamic schema mode

* Fix a test
