Bug when using Stripe one time payments

[Lucho-git]

Hey guys I love that you've open sourced this and made it available for us to use for free, incredible work you are doing. I'm building my own SaaS using it and it's given me a massive head start.

Wanted to let you know that in the pricing/pricing_plans.ts file if you use a stripe_price_id that is a one time payment in stripe it will error.
All of the other recurring payments work great, monthly, yearly, package, tiered, etc.

  "Unknown Error (SSE): If issue persists please contact us.",

I made it into an issue, since that might be a better place to put it.
