[bisq-network/bisq] Issues submitting proposal with less than 7.46 BSQ available (#2613)

Devin Bileck notifications at github.com
Tue Apr 2 00:03:43 UTC 2019 

When attempting to create a compensation request with exactly 2 BSQ in my wallet, the compensation request is submitted without error but upon generating the next block, the transaction gets marked as invalid.

To reproduce, using regtest, I sent 10 BSQ to a new wallet and then sent 8 back so I had only 2 BSQ (to work around the minimum dust limit). I then submitted a compensation request.

The following was in the log:
```

```

I then repeated the process of transferring BSQ to ensure I only had exactly 3 BSQ and this time I was unable to submit the compensation request:

```

This above error occurred until I had at least 8 (I assume more accurately 7.46) BSQ available at which point submitting a compensation request was successful.

So we need to prevent the invalid transaction in the first case (exactly 2 BSQ), and improve the error in the other case (less than 7.46 BSQ).
