/**
 * Transforms a basic "where" query into a format in which the "where builder" can understand.
 * Even though basic queries are valid, we need to hoist them into the "and" / "or" format.
 * Use this function alongside `validateWhereQuery` to check that for valid queries before transforming.
 * @example
 * Inaccurate: [text][equals]=example%20post
 * Accurate: [or][0][and][0][text][equals]=example%20post
