Creating a new app instantly navigates

[rolznz]

There seems to be a bug sometimes creating a second app connection after the first was successfully setup (and received an event). It looks like a bug with the old app pubkey being cached somewhere, causing an instant navigation on the /created page.

A temporary workaround is to do a hard refresh before creating a new app connection

SQLITE cascading delete is not working, so when deleting an app and creating a new one, old request events are linked to the new app.

I realized to do this properly we should also delete the response events, which currently have an issue with the constraint to payments, which is solved by #226

Update: cascading delete is working initially, but seems like a bug with re-using IDs. This should be solved if we add AUTOINCREMENT to all our primary keys.
