Keep libpredict tracking casts when HealComm is loaded

With HealComm-1.0 present (HealComm, LunaUnitFrames, NotGrid), the
compat hook unregistered every event on libpredict.sender to stop pfUI
broadcasting a duplicate of the player's casts. Since cast detection
moved onto that frame's UNIT_SPELLCAST_* handlers, that also blinded
libpredict to every cast, so the player's own resurrections never put
the rez icon on the target's frame: ParseChatMessage drops the player's
own Resurrection echo, expecting the cast events to have tracked it.

The compat hook now only mutes the outgoing HealComm and CTRA messages.
The HealComm.SendAddonMessage hook that parsed the player's own messages
while solo goes too, since libpredict tracks its own casts directly.
