Adapt the way we query the last internal transactions for an address

[Viterbo]

Description

Currently, we fetch transactions one by one to get the last 20 internal transactions. This should be changed to query just one bulk list of the last internal transactions for an address.

This issue depends on https://github.com/telosnetwork/teloscan-indexer/issues/259

Uptade:

route will be /v1/address/{address}/internal
