[hsbc] Miscellanous fixes for new webspace

Following release of new webspace parsing, certain changes must be done
for fixing more connections:
- Match '1234567891011EUR' as well as '1234567891011USD' for account
numbers when accessing their transaction history
- A logger in order to prode with Graylog if connections are still using the Fusion webspace. We'll need to depracate that part of the code if they don't.
- A few typos
