  Fix DTMF not being sent to other side after a partial feature match
  
  This fixes a regression from commit 176701. The issue was that
  ast_generic_bridge never exited after the feature digit timeout had elapsed,
  which prevented the queued DTMF from being sent to the other side.
  
  This issue was reported to me directly.
