[lttng-dev] [PATCH lttng-tools] Tests: Add filtering tests for uncovered cases

[christian.babeux@efficios.com (Christian Babeux)]

While investigating the code coverage of the filtering feature,
a couple of possible tests cases were uncovered:

Error tests:
* Strings can't be IR root node
* Unary ! not allowed on string type
* Comparison with string type not allowed
* Logical operator not allowed with string types
* Nesting of binary operator not allowed

Valid tests:
* Cover all left/right operands permutations with
  fields ref. and numeric values.
