Changes to getCurrentUser

[DubyaDude]

This removes the individual refresh loop of getting the current user.
In the loop, getting the current user will be grabbed along with refreshing the friends list, which has a cooldown of an hour.

This is waiting on the following to be implemented/tested

• The addition of user-location WebSocket event firing when the user is traveling or offline.
  • VRChat's Implementation.
  • VRCX's Test/Implementation.
• The addition of instance-queue-left WebSocket event.
  • VRChat's Implementation.
  • VRCX's Test/Implementation. (06dad59)
• [OPTIONAL] The addition of the presence object being sent over the WebSocket.
  • VRChat's Implementation.
  • VRCX's Test/Implementation.

We were told that instance-queue-left event has now been added in VRChat 🎉
