Before spice_main_channel_clipboard_selection_request was always called so
spice_channel_wakeup was also called. Honestly I don't have enough knowledge
to understand if this could be an issue or not. Not clear which events
could be possible pending here, the function looks quite an hack, looking
at the signals set there's "notify::agent-connected" which seems to mean
that meanwhile the "agent-connected" value is expected to change during this
function.
