  fixes subscriptions being lost after 'module reload'
  
  During a module reload if multiple extension configs are present,
  such as both extensions.conf and extensions.ael, watchers for one
  config's hints will be lost during the merging of the other config.
  
  This happens because hint watchers are only preserved for the
  current config being merged.  The old context list is destroyed
  after the merging takes place, meaning any watchers that were not
  perserved will be removed.
  
  Now all hints are preserved during merging regardless of what config
  file is being merged.  These hints are only restored if they
  are present within the new context list.
