the other.

The test sets up a source with a sometimes pad added during
the transition of a wrapper bin from READY to PAUSED.

It runs 4 iterations, the last of which makes it so the
negotiation fails.

In that case, the intention as correctly presented by the following
comment:

/* [..] ie, the pipeline should create ok but fail to change state */

However the implementation of run_delayed_test was neither calling
get_state on the pipeline (it called it on the wrapper bin), nor
checking that the return of get_state was FAILURE (it actually
checked that it was not).

This led to an obvious race condition, and was fixed by calling
get_state on the pipeline, then checking that in this specific
case (expect_link == FALSE), the state change has actually failed.

The second, rarer race condition is at set_state time. When we
don't expect the link to succeed, the return of set_state may
either be FAILURE or ASYNC, depending on timing. This was fixed
by taking expect_link into account when checking the return value
of set_state.

0 stored in the GstBus that is currently in the process of being
destroyed. gst_bus_remove_watch() might then access it, increase its
reference count to 1 again, call GSource API on it and then unref it,

returned so the above would be safe now.
