[boursorama] Corrected issues with immediate card transactions

All immediate card transactions were filtered out from their parent
account because of issues in transaction typing as well as deferred card
transaction filtering.
For each account, ALL card transactions appear so we must carefully sort
transactions from deferred/immediate cards and only yield the immediate
ones since deferred card transactions are yielded separately (in the
history of the card).
This code enables correct detection of deferred card transactions
(mainly by checking if the account_label of the transaction appears in
the list of deferred cards).

Note: I also re-organized the order of iter_history() methods in browser.py
because it was a huge mess.
