action_redirect: remove after_bridge_goto_info

Under certain circumstances the context/extens/prio are stored in the
after_bridge_goto_info. This info is used when the bridge is broken by
for hangup of the other party. In the situation that the bridge is
broken by an AMI Redirect this info is not used but also not removed.
With the result that when the channel is put back in a bridge and the
bridge is broken the execution continues at the wrong
context/extens/prio.
