Make client delay less before sending PUSH_REQUEST

Make client delay less before sending PUSH_REQUEST

Speed up PUSH_REQUEST handling on the client side by reducing
the amount of dependent 1s-coarse-timers to "just one".

After "TLS is up!", one timer needs to fire to wakeup
"check_connection_established_dowork()", and that one used to
setup another 1s timer before sending PUSH_REQUEST - which is
just dead time where we sit idly...  So, fire immediately.
