Swaps fail on the ASB side with "not enough money" and don't necessarily continue

[guardian-beach]

Describe the bug
The swap backend asb starts a swap, and appears to discover midway through that it does not have enough money to complete the swap, probably due to price fluctuations.

Instead of refunding or cancelling the swap, asb simply waits. In many cases, only when asb is restarted does it start showing messages about cancelling or refunding.

Lost/trapped Funds
Unclear. Taker funds may be stuck until asb restarts, or a timelock expires.
