When progressing in a raid and the first boss is killed, and you get locked into that instance, the abbreviated list does not update and turn green names into red - or add a red name (depending on display setting.)

I.E. The abbreviated instance names are not updating to reflect new instance lockouts on UPDATE_INSTANCE_INFO event callback. A ui reload is required (any load screen or /rl).

The issue seems to lie somewhere in TRaidLockout_UpdateButtonText() as the tooltip is updating correctly on the same event.
