Summary:                    "restart gracefully" can crash asterisk
Description: 
I think, that __ast_context_destroy() function in main/pbx.c contain some
bug, but now can found there...

You can reproduce coredump file whith following CLI command:

*CLI> module unload app_queue.so
*CLI> restart gracefully

backtrace added.

I think, in this line:

"if (strcmp(tmp->registrar, registrar) == 0 && tmp->refcount < 2 &&
!tmp->root) {"

"tmp->registrar" points to unallocated memory, but why?
