Queues: Agents with no team assignment

Commit d8b61e8 correctly addressed an issue with criteria for team assignment
when an agent doesn't belong to a single team, BUT failed to consider cases
that the criteria is part of a set of constraints. e.g Tickets assigned to
Me OR one of my Teams.

This commit adds a check to skip team check when multiple constraints are
included.
