config: fix jwt_issuer_format conversion (#5524)

Remove the previous conversion logic in NewPolicyFromProto() for the 
jwt_issuer_format field. This would prevent the new "unset" state from
working correctly. Add a unit test to verify that all three values
(unset, "hostOnly" and "uri") will successfully round trip to the proto
format and back again.

Also add a test case for the Options.ApplySettings() method to verify 
that an unset jwt_issuer_format will not overwrite the existing value
(if any) in the settings.
