Title:
  Nova operations fail when profiling is enabled

Status in OpenStack Compute (nova):
  Invalid
Status in osprofiler:
  Fix Released

Bug description:
  Nova server-related operations fail with HTTP 500 when executed with
  profiling. Nova server log contains error "IndexError: pop from an
  empty deque" and stack trace pointing to osprofiler code:

  ERROR nova.api.openstack   File "/opt/stack/osprofiler/osprofiler/web.py", line 132, in __call__
  ERROR nova.api.openstack     return request.get_response(self.application)
  ERROR nova.api.openstack   File "/opt/stack/osprofiler/osprofiler/profiler.py", line 348, in __exit__
  ERROR nova.api.openstack     stop()
  ERROR nova.api.openstack   File "/opt/stack/osprofiler/osprofiler/profiler.py", line 87, in stop
  ERROR nova.api.openstack     profiler.stop(info=info)
  ERROR nova.api.openstack   File "/opt/stack/osprofiler/osprofiler/profiler.py", line 406, in stop
  ERROR nova.api.openstack     self._notify("%s-stop" % self._name.pop(), info)

  
  Steps to reproduce:
   0. Take the latest Devstack with osprofiler enabled.
   1. Execute `openstack --os-profile SECRET_KEY server list`

  Observed behavior:
    $ openstack --os-profile SECRET_KEY server list
    The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-73de8073-94b7-44f0-96ca-5a0c5979636c)
