[Proposed fix] Frequent disconnects when receiving messages in json-rpc mode

[justgos]

The problem

hallo!

it appears that the nc used in json-rpc mode frequently falls off.

modifying /src/scripts/jsonrpc2-helper.go

-command=bash -c "nc -l -p %d <%s | signal-cli --output=json -u %s --config %s jsonRpc >%s"
+command=bash -c "watch -n1 nc -l -p %d <%s | signal-cli --output=json -u %s --config %s jsonRpc >%s"

fixed it for me
