Fix Injector.getPlayer() using TemporaryPlayer when a Bukkit player is available

[LeonTG]

On my server I had a lot of issues where I was getting a temporary player for packets sent before PlayerJoinEvent, even tho Bukkit.getPlayerExact was returning the actual joined player

So I did some digging and I found out that even tho it returned the temporary player, playerName variable was set, and with more digging it turns out that even if a bukkit player is available, doing getPlayer on the injector would never check for Bukkit player if a temporary player was already assigned

so I decided to fix it myself, this is how I did it, and I figured I should make a PR for it, so others wont have this issue

For reference, this is what debugging I added

and it resulted in this

Found temporary player with name resolved... attempting to fix: kawaiibunri (Team: npcNameTag, Mode: 0, Class: com.comphenix.protocol.injector.temporary.TemporaryPlayerInvocationHandler)
Potential is: com.comphenix.protocol.injector.temporary.TemporaryPlayerInvocationHandler@55466d92
Temporary player is now: CraftPlayer{name=kawaiibunri} (Equal? false)
