I found some more bugs with the parsing of folded scalars. I'd also made some mistakes in the tests introduced by me in #6785. This PR fixes the incorrect tests, and introduces more related tests.

I had to completely rewrite the `Parser::parseFoldedScalar()` method. I think it came out simpler in the end - less 'special cases'. I've done some basic profiling by running the parser tests on repeat and haven't noticed any difference in parsing performance.
