* tests: Bump mocktime in smaller intervals while (not) signaling This is needed to avoid triggering `CMasternodeSync::Reset()`. * tests: force faucet node to finish mnsync in prepare_datadirs * test: Drop redundant force_finish_mnsync in interface_zmq_dash.py Co-authored-by: xdustinface <xdustinfacex@gmail.com>
