Minor Fix for AND/OR/XOR

[oleibman]

These 3 fall into the set of functions where Excel treats string literals differently depending on whether they are passed to the function directly or as a cell reference. PhpSpreadsheet is updated to try to duplicate that logic. New tests are added. Some existing test results had to change as a result of this code change.

This is:

- [x] a bugfix
- [ ] a new feature
- [ ] refactoring
- [ ] additional unit tests
