The OAuth/OpenID AuthenticatorProvider has no UserContext and so GuacamoleTrigger fails

[adb014]

The problem is in the title. The fix I'm using is

diff --git a/src/main/java/org/apache/guacamole/guacamoletrigger/auth/TriggerUserContext.java b/src/main/java/org/apache/guacamole/guacamoletrigger/auth/TriggerUserContext.java

The edit of the message was to fix the patch that was initially incorrect

[adb014]

See the definition of getUserContext for OAuth/OpenID to see that this is so
