Gst.Promise not returning a value

[Ashwin Dharne]

Hey! I've been fiddling with the webrtcbin plugin and for some reason, my
Gst.promise.new_with_change_func()'s callback can't access the value that
is stored in the promise. I suspected that the promise wasn't changing
state properly, but when I print out the return value of promise.wait(), I
get:
<enum GST_PROMISE_RESULT_REPLIED of type Gst.PromiseResult>
So it seems like promise.get_reply() should return a value but when I print
it, it prints None. What could be the issue? Thanks!
