General fixes (#54)

Depends on #55

These changes are really small and I don't know how to reasonably split
them into multiple PRs, but here's the changelog:
- The result of the `UtilityService#LogActionAsync` call in
`BanCommandGroup#BanUserAsync` is no longer ignored and it's errors will
now prevent feedback from being sent;
- Converted `if` statement to a `return` with ternary in
`LanguageOption`;
- Slightly decreased method complexity of
`MessageDeletedResponder#RespondAsync` by cleverly using Results;
- Changed the order of parameters for `UtilityService#LogActionAsync` to
flow better;
- Removed the exemption for `ConvertIfToReturnStatement` for
InspectCode.
