Symbol vs String

In most query building methods, we allow symbols and strings to be given as parameter.

While not being always true, when using Symbol, Clear will try to escape the word using double quote during the request building, while String will be printed out as it.

# SELECT * FROM "users" INNER JOIN "orders" on "order_id" == "orders"."id"
User.query.join(:orders){order_id == orders.id }
# SELECT * FROM "users" INNER JOIN orders on "order_id" == "orders"."id"
User.query.join("orders"){order_id == orders.id }

In case of wrong behavior, do not hesitate to fill an issue here.
