Fix bug #14699.
* pcs/query.c (QueryState): Added a state QUERY_WAIT_FOR_BACKEND
to indicate that the query is not populated as we are waiting for
the backend to be opened.
(query_init): Start in the QUERY_WAIT_FOR_BACKEND state.
(query_destroy): Only disconnect from the backend if we are in a
state that implies that we are connected to its signals.
(query_construct): If the backend is already loaded, immediately
set the state to QUERY_START_PENDING.
(backend_opened_cb): Disconnect from the backend's "opened"
signal. Set the state to QUERY_START_PENDING.
(match_component): We can now only match components if the query
is in progress or if it is done. Assert to that effect, and do
not ensure_sexp().
(match_component): Do not check for a nonexistent component using
g_return_if_fail(). Also, there is no need to ref/unref the
component.
(backend_obj_updated_cb): Assert to the effect of our state.
(backend_obj_removed_cb): Likewise.
(parse_sexp): Renamed from ensure_sexp(). Assert that the query
has not started. Do not disconnect from the backend's signals
here, since we have no connections.
(start_query_cb): Set the state to QUERY_IN_PROGRESS here instead
of in populate_query().
