Mecenary task tracker needs update after task rework

[durandal42]

Describe the bug
Task tracker shows all active tasks, but this is now an enormous number of tasks (1 per owned mercenary), so most of them spill off the screen and make the tracker useless.

To Reproduce
Steps to reproduce the behavior:

1. Start any bounty.
2. Begin first game.
3. Click "Tasks" in HSTracker overlay.
4. (See attached screenshot)

Game mode

• Standard
• Wild
• Classic
• Arena
• Battlegrounds
• Duels
• Mercenaries
• Tavern Brawl
• Dungeon Run/Book of Heroes/Book of Mercenaries
• Single Player

Expected behavior
Only tasks for my active party are displayed, or sort the tasks such that those are on screen.

Screenshots

Notice that my party is [Cariel, Xyrella, Samuro, Cairne, Bwonsamdi, Gul'dan], but only Cariel and Xyrella's tasks appear on screen; the rest are for mercs not in my party.

Version (please complete the following information):
2.3.8 (2611)
