New issue 1675: Query parameter serialization
https://bitbucket.org/openid/connect/issues/1675/query-parameter-serialization

Andrii Deinega:

All query parameters in

1. Fetch Entity Statements Request
2. Resolve Request
3. Trust Mark Status Request

 should be serialized using the _application/x-www-form-urlencoded_ format.

[https://openid.net/specs/openid-connect-core-1\_0.html#QuerySerialization](https://openid.net/specs/openid-connect-core-1_0.html#QuerySerialization) is how the OpenID Connect spec does it.
