terminating `roller run` sometimes leave zombie processes

[mtsitrin]

running roller run succesfully after a while, terminating it using ctrl-C

sometimes there are relayer leftovers:

e.g

 ~/Applications/dymension/roller  mtsitrin/392…ple-channels *7 !4 ?1  roller run                                                                                                                                ✔

Seems to stem from the relayer operation only after the channel establishment
