Incorrect parsing with extra parentheses

**Describe the bug**
When I add an extra left and right parentheses in the middle of a query around a comparison, the mql parser doesn't generate the same logical representation.

Example:

URL Query (parentheses around test_b="TestB"):
`(test_a="TestA" and (test_b="TestB")) or (test_c="TestC" and test_d="TestD")`

SQL Query Generated:
`(test_a=? and (test_b=? or (test_c=? and test_d=?)))`

**To Reproduce**

Thanks!
