Steps to reproduce

Summon a trust, attempt to use Cover on it. See that Cover will not cast on them and you get a message saying:

Expected behavior

Player should be able to use Cover on trusts (Tested on retail and confirmed it can).

I think we are simply excluding trusts under:
xi.job_utils.paladin.checkCover = function(player, target, ability)

which causes the player to be unable to use it on them.
