update to use /api/{projectId}/store

The default recommended rate limiting on the sentry
    documentation rate limits by `projectId`.

It's a better default to talk to a sentry server using the
    `/api/{projectId}/store` API.

This way multiple services talking to the same sentry
    server will not all get rate limited under the same
    projectId (which is presumably the empty string).
It wasn't exactly a duplicate run becuase coffeescript modifies the stack traces and injects stuff in. So we run the entire test suite with the coffee script runner as well to make sure that's ok. :)
