Filter loadUser lookups to the Sakai user provider with the user pattern

Description

If you edit presenter metadata, Opencast tries to resolve the presenter name as a user, for example:

This leads to loadUser() from user providers being called with what is usually a descriptive name (firstname lastname), not a username.

Apply the user pattern regexp to filter these so the user provider doesn't attempt to resolve them.
