Adds a few test cases where we do comparisons on non-existing variables.
Before when we encountered a non-existing variable in a comparison it would result in an error: "no variable found for name 'x'". This commit changes this so we can deal with non-existing variables. They now get treated as ValNull and the comparison succeeds without errors.
Expectations of these existing test cases were wrong. They would expect errors or booleans as a result, where we now return a ValNull. Not all behaviours were clear! As a result some test cases have been ignored until this is clarified.

@remcowesterhoud awesome. 🎉
I like that the new tests are in a separate test class. 👍
Before merging, please add one more test case for the between operator.
