chore: leverage expressionFromString more in drizzle adder

[benmccann]

A bit of the code here was unused. See #555

I haven't gotten a chance to test this yet, but thought I'd share my progress before I have to run for the day. Manuel thought that we might need to tweak expressionFromString to delete the Literal.raw property so that it can pick the proper quote type. I've not checked that yet and assume we'll need to update it

Made the following changes:

• fixed the drizzle output so that the tests can run
• for some reason, we format all test results with prettier (valid for js / html / css). This is probably a leftover from when the js block often was poorly formatted.
• now that prettier is not run anymore, i added a failing test that Ben already mentioned in the PR description. We might be able to fix this by calling stripAst from within expressionFromString but that might be too aggressive as this will be done on all child nodes, instead as only on Literals
