Combine two where clauses into an OR constraint. Equivalent to the `$or`
 Parse query operation. This is useful if you want to find objects that
 match several queries. We overload the `|` operator in order to have a
 clean syntax for joining these `or` operations.
 @example
  query = Player.where(:wins.gt => 150)
  query.or_where(:wins.lt => 5)
  # where wins > 150 || wins < 5
  results = query.results

  # or_query = query1 | query2 | query3 ...
  # ex. where wins > 150 || wins < 5
  query = Player.where(:wins.gt => 150) | Player.where(:wins.lt => 5)
  results = query.results
 @param where_clauses [Array<Parse::Constraint>] a list of Parse::Constraint objects to combine.
 @return [Query] the combined query with an OR clause.
