pytest: fix flaky wait_for_log() in test_funder_feerate_reconnect.

Browse Source 
The comment was wrong: the channel being locked in was triggering
the fee update and hence the disconnect.  But that can actually
happen before fund_channel returns, as that waits for the gossipd
to see the channel active.

Best to do the fee update manually, so it's exactly what we want.
