Description:

media: make "init-media" signal handler optional

Change the logic so that the PurpleMedia instance isn't disposed when
"init-media" has no connected handlers.

We want the media object freed only when some signal callback function
explicitly returns FALSE, indicating an error during the initialization.

This is mostly useful for the imminent addition of private media streams.
