paycore: Default groupid to increment from last one

Browse source 
This re-establishes the prior behavior where a `sendpay` or
`sendonion` that'd match a prior payment would cause the prior payment
to be deleted. While we no longer delete prior attempts we now avoid a
primary key collision by incrementing once. This helps us not having
to touch all existing tests, and likely avoids breaking other users
too.
