pushkey: run hook after the lock release

The pushkey operation used to be in its own wireprotocol command and (in
practice) always be lock free when running the hook. With bundle2, it happen in
a greater scheme and a hook running locking command would get stuck. We now run
such hooks after the lock release as similar hook do.

Bundle2 test are altered to ensure we are lockfree at hook running time.
