Bug report: Can't restore Bedrock player backup if the player is offline

[AlphaMSq]

Server details:

• Server version: Current Purpur Version: 1.21.5-2431-eca7806 (MC: 1.21.5)
• IRP Version: Running InventoryRollbackPlus v1.7.2

Bug description:

Backups for Bedrock players are not detected by the plugin when the player is offline.
Expected behavior: The plugin should detect and allow restoring backups for Bedrock players even if they are offline.

How to reproduce:

1. Set up a 1.21.5 server and install the following plugins: Geyser, Floodgate, and InventoryRollbackPlus.
   Configure Geyser and Floodgate to enable Bedrock player connections.

2. Join the server using a Bedrock client.
   While the player is online, attempt to restore their inventory - the plugin successfully detects and restores it.

3. Log out the Bedrock player.
   Now try to restore their inventory again - the plugin does not find any saved backups.

Your server doesn't support fake players correctly. You can always just provide a UUID of the player directly instead of the name and it will bypass the name-to-uuid lookups, in effect skipping the procedure your server is struggling with.
