Previously an inner nested `NOT`, e.g. `WHERE NOT (x NOT IN (...))` was dropped by the adapter. This change identifies such situations and recurses into the tree so that nested boolean terms are preserved correctly.
Upstream Hyrise's precedence for NOT and unary minus differed from MySQL. It has been changed with this update, and accompanying qserv-side tests have also been added.
