Improve test coverage

[Falci]

I noticed in the coverage report that a lot of the wallet make___() errors are not covered (eg "Auction is not yet open" and "Name has not reached bidding phase", etc). This could be another "good first issue" that would be easy to do and get a few more lines covered.
