Problem: Not all Lua code is checked by stylua. Automating code-style is an important mechanism for reducing time spent on accidental (non-essential) complexity. Solution: - Enable lintlua for `test/unit/` directory. - TODO: only `test/functional/` remains unchecked. previous:45fe4d11adprevious:517f0cc634
