When you select a priceset with the value 0, the form properly hides
the credit card input fields.

However, we still try to submit a credit card to stripe which results in
an error.

ensure our js code always runs first

allow multiple stripe payment processor on back end

If we wait for the event handler to kick in, other js code
might run first (like offline event registration does an ajax
call to register a participant).

Without this patch, you can the error "no such token" if:

 * You have two different stripe payment processors configured.
 * you are making an offline contribution
 * using the provided payment processor back end, you choose the
 non-default payment processor.

The stripe javascript submits the payment using the default payment
processor, but the PHP codes tries to charge it using the user-selected
payment processor, which leads to the error.

This fix also ensures that if a non-stripe payment processor is chosen
we won't try to send it to stripe.

handle error corner cases

Katalon browser based automation testing

Very incomplete, but hopefully is a useful start.
