Description:
Sindragosa in Icecrown Citadel, once it casts Ice Tomb on a player, logout or disconnect the player and let the team wipe to stop the engagement, log the player back and Ice Tomb stays on player. At this point, player will not affect any damage from Sindragosa and this player can heal other players.

Expected behaviour:
Ice Tomb aura gets clear out from player when logged off/disconnected

Steps to reproduce the problem:

1. .go creature id 36612
2. Set instance boss state DONE from 0 all the way to 10: .instance setbossstate 0 3 to .instance setbossstate 10 3
3. Use teleport and go to Sindragosas' lair
4. Kill creeps and both Spinestalker and Rimefang to bring down Sindragosa
5. Bring in a second character
6. .cheat god on both character
7. Engage Sindragosa and wait until it takes off and ice Tomb on one of the char
8. Logout out or disconnect the one get Ice Tomb
9. Wipe the group to clear the engagement, or .die yourself
10. Log back the disconnected char, Ice Tomb remains on the player (while logging back in, .cheat god is no longer applied)
11. Use the character that has no Ice Tomb to engage Sindragosa, the character with Ice Tomb will not take any damage from Sindragosa. As long as this char is not attacking Sindragosa, it can assist other players such as healing
