[BUG] Spectator bug & Arrows not disappearing

[majkefer]

Describe the bug

• Spectator can interfere with gameplay in Crystal & Cart PvP. Specifically, they can stand on top of an obsidian block to prevent players from placing Crystals & they can destroy TNT Minecarts.
• Arrows not disappearing after rounds end in a single match with more rounds, but they disappear after the duel is finished.

To Reproduce Spectator bug

1. Spectate a duel. 2a. Stand on obsidian. || 2b. Let one of the duelists place a TNT cart. 3a. One of the duelists tries to place crystal where you are standing || 3. Hit the minecart. 4a. They are unable to place it. || 4b. The minecart is broken.

Arrow bug

1. Start a duel with bows.
2. Shoots arrows at the ground.
3. End the round.
4. The arrows should still be on the ground in the next round.

Expected behavior We expect arrows on the ground to disappear after each round, not after the entire duel. Spectators shouldn't be able to interact with the game environment.
