[CBR-468] Add sliding window tx requests

[kderme]

Description

This pr makes the getTransactions endpoint to work on a loop, untill it fetches all wanted results. Untill now, if a TxMeta entry failed to be transformed into a V1.Transaction, the request failed. Now we are more lenient: we ignore such TxMeta. This means we can have less entries than wanted. That's why we keep going back to SQlite for more TxMeta entries untill we have a full page or TxMeta are over.

TODO: needs to add tests.
