Subject: [PATCH] Fix SPIGOT-5989
Before this fix, if a player was respawning to a respawn anchor and
the respawn location was modified away from the anchor with the
PlayerRespawnEvent, the anchor would still lose some charge.
This fixes that by checking if the modified spawn location is
still at a respawn anchor.
