Split the database trait into read and transactions. (#826)

Browse Source 
* Split the database trait into read and transactions.

The transaction traits will encapsulate all database changes and also expect
READ-and-lock operations to read and lock records from the database for
exclusive access, thereby avoiding race conditions.

The Transaction trait expects a `rollback` operation on Drop unless the
transaction has been committed.

* fix: melt quote duplicate error

This change stops a second melt quote from being created
if there is an existing valid melt quote for an invoice already.
If the first melt quote has expired then we allow for a new melt quote to be created.
