Waits for tmux to reach a state instead of sleeping.

tmux answers a command as soon as it has accepted it, not once the effect
has landed, so a test that acts and then reads immediately is racing the
server. A fixed delay only hides that on an idle machine; waiting for the
state itself is what makes the test say what it means.
