Purge the awful refreshAccount logic

Browse source 
User.prototype.refreshAccount was responsible for multiple race
condition bugs as well as inefficient duplication of DB queries in an
attempt to correct such race conditions.

It has now been replaced by a more reasonable model:

  * Global user account information and aliases are fetched in parallel
    on socket connection
  * Channel rank is fetched when the user tries to join a channel
