  b2b_logic: fix a crash when using the "n" flag for b2b_bridge()

The crash would occur when using the "n" flag even though the current
entity has already been deleted with b2b_delete_entity().

  Log Message:
  -----------
  b2b_logic: fix bad NOTIFY body for 100 Trying

The static variable representing the new message body would point to the
buffer of the SIP message from the previous call to process_bridge_notify(),
resulting in garbage data.

Credits to @nikbyte for catching the issue.
Alternative fix to #2503.

  Log Message:
  -----------
  b2b_logic: properly end dialog with notified entity

Send BYE instead of just deleting the entity after completing the
bridging action, when using the "n" flag for b2b_bridge().
