Update expected txs in test

[dangeross]

In test_address_transactions change the expected result. Looks like the mempool.space results are now block height ascending

We should really not be calling remote endpoints in unit tests. But for now this is good. LGTM.

In their docs they mention that the sorting order is the newest first: https://mempool.space/docs/api/rest#get-address-transactions

I noticed the test failing as well. The order can change. Meaning that the test sometimes fails and other times succeeds. Maybe we can simply sort the result like shown here.
