hackEarlySend login with wrong UUID #141

Description

Describe the bug

When hackEarlySend is set to true, the user will log in with the wrong UUID (I assume an offline one) rather than online. Unfortunately, disabling it does not let us use LuckPerms, but in return uses the right UUID.

Expected behavior

Users should have their correct UUID upon login, so the data in luckperms isn't using the wrong uuids and players are able to have the right data loaded, including their skins.
