BetonQuest version information

BetonQuest version: 2.0.0-DEV-331
Server version: git-Paper-386 (MC: 1.18.2)

Hooked into: Citizens (2.0.29-SNAPSHOT (build 2493)), LuckPerms (5.4.9), PlaceholderAPI (2.11.1), ProtocolLib (4.8.0), Vault (1.7.3-b131), WorldEdit (7.2.10-SNAPSHOT+6117-e21ab6a), WorldGuard (7.0.6+1cff55f), mcMMO (2.1.210-SNAPSHOT)

Expected behaviour

No SQL query is ever executed on the primary server thread.

Actual behaviour

Every time BetonQuest.getPlayerData() or BetonQuest.getOfflinePlayerData() is called for a player that is not yet present in the playerDataMap a new PlayerData object is created.
During the creation of that object loadAllPlayerData() is called, which executes SQL queries. As no care was taken for when that method is called, it is used from the primary server thread on many occasions.

Steps to reproduce

1. Configure a debugger to only break on the primary server thread in the PlayerData constructor.
2. Start the server and attach the debugger.
3. Join the server. Order is important, this has to happen after attaching the debugger!
4. Do some quests until the debugger triggers (the first time your player data is used).
5. Step through the loadAllPlayerData() and watch the SQL queries execute.
