* Extracts the _compound certificates_ from two lists of _base certificates_.
* This is required because **db-sync** stores _compound certificates_ splitting them in _base certificate records_.

* certificate record splitting `stake_vote_deleg_cert` properties: the `pool_keyhash` is stored in the first record
* and the `drep` is stored in the latter record.
*
* To make the lower amount of queries as possible, we perform one single query on each certificate table, next we use
* this function to merge them results.

* @param certs1 The first list _base certificates_.
* @param certs2 The second list of _base certificates_.
* @param merge The function to merge two _base certificates_ into a _compound certificate_.
