[Camera Tools] Inconsistent behaviour without index and dead players for same class

[Wiethoofd]

Reproducible when there are 2 or more of each class using ce_cameratools_spec_class team class (without the optional [index]) and the first player in the list to cycle through to observe is dead.

	Example 1	Example 2	Example 3	Example 4
BLU Soldier	Alive	Alive	Alive	Alive
RED Scout 1	Alive	Dead	Dead	Alive
RED Scout 2	Alive	Alive	Dead	Dead
RED Scout 3	Alive	Alive	Alive	Alive

In every example we start on 'BLU Soldier' and repeatedly use the bind with ce_cameratools_spec_class red scout
☑️ Example 1: Changes from BLU Soldier to RED Scout 1 to 2 to 3 and back to 1 (as expected)
❎ Example 2: Stays on BLU Soldier and does not swap to RED Scout 2 or 3; when 1 is dead
❎ Example 3: Same as 2; stays on BLU Soldier to does not swap to any scout
🔲 Example 4: Changes from BLU Soldier to RED Scout 1 to 3 and back to 1

NB: have not been able to confirm example 4 in a live STV or demo, only in local server.

Example STV demo

At the start a blue scout and red soldier in the first slots are dead and the 'team class' bind will not cycle through the players, but a 'team class 1' for the 2nd player on that class will swap to the correct POV.

Fixed in dalegaard@6c3440f, ignores dead players when switching. You can cherry pick it from there, or I can make a PR if you prefer.
