Bitcoin Testnet backends were removed. This broke our tests that work purely on local data but nevertheless need to know backend URLs. Because the design is less than ideal. Here, we do a little cleanup: * blockbook URLs are respected * Dogecoin is now supported by our blockbook backend so we don't need a special tx-api implementation * it's possible to instantiate a TxApi that is backed by the cache, without a known URL * relevant tests now make use of this feature
