Improve feedback of failed assertions in LUA

[hobovsky]

Messages from failed assertions are presented with <LOG::> instead of being a part of <FAILED::> :

Can this be improved, or maybe such behavior is caused by some quirks of LUA testing framework?

The issue seems to be similar to #222 but I am not sure it has the same cause.

I'm pretty sure it's the same reason as #222, working around codewars/codewars-runner-cli#305 (comment) which doesn't exist anymore.

I'll create a repo for the reporter.

You should be able to make changes and test locally with luarocks.

I'll close this when it's deployed.
