Generated SQL for WHERE clause doesn't match AST nesting about mammoth

More serious variant of the issue:

  const subExpr = () => {
    return db.test.a.or(db.test.b);
  }
  await db
    .select(db.test.a)
    .from(db.test)
    .where(db.test.xyz.and(subExpr());
  await db
    .select(db.test.a)
    .from(db.test)
    .where(subExpr().and(db.test.xyz)));

SELECT test.a FROM test WHERE test.xyz AND test.a OR test.b 
SELECT test.a FROM test WHERE test.a OR test.b AND test.xyz 

I would expect the OR to be parenthesized because it is deeper in the function call tree:

SELECT test.a FROM test WHERE test.xyz AND (test.a OR test.b)
SELECT test.a FROM test WHERE (test.a OR test.b) AND test.xyz 

Without that, it makes it hard to reliably write functions that return subexpressions.
