a wallet that runs out of funds completely is not handled gracefully

[krunch3r76]

entropythief will report this:

The model threw the following exception:
ApiException
(400)
Reason: Bad Request
HTTP response headers: <CIMultiDictProxy('Content-Length': '51', 'Content-Type': 'application/json', 'Date': 'Thu, 05 Aug 2021 04:29:01 GMT')>
HTTP response body: {"message":"Insufficient funds to make allocation"}

not sure how i want to handle this generic exception or how i might be proactive about it.
