Some tests are meant to fail, however some failures were actually
crashing the test driver.
This fixes the issue.

Make failure in unions commutative
...
Right now, because of how _rearrange was implemented, a union with a subset
of attributes of another union could be united with it, but not viceversa.
This change makes both operations fail, hence making the union commutative
again.
Correct unions were always commutative.

Better handling of parenthesis inside string literals
...
When scanning for the matching parenthesis, string literals
were not taken into account, which would inevitably lead to
errors if one wanted to do a selection on a string containing
a parenthesis.
Now it uses a state-machine to skip the ones that are located
inside literals.

Avoid proliferation of parenthesis
...
The str() function of the parse tree now emits expressions
with much less parenthesis.
This should allow optimized queries to be more readable.
