More stable connection between maker and taker

[da-kami]

I keep encountering the following problems locally with regtest.
I am not sure if all problems have the same source, but it feels like we lose connection to the maker.

1. Not connected to node error when trying to open a channel:

flutter: {_OpenChannelState} {openChannel} {Failed to open channel.} {FfiException(RESULT_ERROR, Could not create channel with 02cb6517193c466de0688b8b0386dbfb39d96c3844525c1315d44bd8e108c08bc1@127.0.0.1:9045 due to Channel unavailable: Not connected to node: 02cb6517193c466de0688b8b0386dbfb39d96c3844525c1315d44bd8e108c08bc1, null)} {LogLevel.ERROR} {29 November 2022 03:02:27 PM}

This error could be resolved by only restarting the maker (not the taker).

2. Peer for first hop currently disconnected/pending error when trying to open a CFD

2022-11-29 04:11:14  INFO ten_ten_one::cfd::open: Adding custom output
flutter: {_CfdOrderConfirmationState} {openCfd} {Failed to open CFD.} {FfiException(RESULT_ERROR, Peer for first hop currently disconnected/pending monitor update!, null)} {LogLevel.ERROR} {29 November 2022 03:11:14 PM}

This error I was only able to overcome by restarting both taker and maker - I tried to only restart the maker but was still unable to open the CFD. Once I restarted the taker as well it worked.
Note: On another instance I was able to overcome this error by just restarting the maker!

3. Channel not available error when trying to settle a CFD #428

This error I was able to to overcome by only restarting the maker.
