itest: wait for channel to be properly closed

Browse Source 
It looks like in some cases a channel is still being closed while we
already try to create a sweep output. In that case the pending closed
channel is still counted as anchor channel and a reserve output is
created. To make sure that doesn't happen, we make sure there are no
pending or open channels of any kind around before we create the sweep
transaction.
