chore: Add tests for all remaining like cases, unify existing, make signature stricter

[luanpotter]

This will:

• refine signature of like functions to use F & Any instead of String - while we know these have to be equivalent because there are no other subtypes of String, Kotlin doesn't know (this enables a future value adapter PR)
• add a new LikeQueriesTest to centralize all test cases related to like and iLike
• add missing test cases to touch all code paths
• standardize spelling of iLike
• standardize test names - remove references to "yawn", as all tests are yawn tests; use a what it test - what the query is pattern I've started to use on all tests
