Add parser improvements (#2679)
* Add parser improvements

Previously everything starting with "$" was parsed as a column path.
With this commit applied, the lite_arg starting with $ is parsed as
the most appropriate thing
- $true/$false ==> Expression::Boolean
- $(...) ==> Invocation
- $it ==> ColumnPath
- Anything with at least one '.' ==> ColumnPath
- Anything else ==> Variable

* Ignore failing tests
