Increase the test waits for timed interaction tests. (#12558)

The tests are failing intermittently because the client starts the
wait when it _sends_ the message and the server starts its timer when
it _receives_ the message.  So if the message takes >5ms to be
delivered initially, the test ends up with an unexpectedly successful
command.

The right fix for this would be for the client to start its delay when
it receives the status response, but that requires more hooks into the
IM state machine than we have (and probably than we want).  For now,
just increase the timeout used by the client to make it very unlikely
that that much time passes before the timer on the server expires.
