[r23114]Bug 704183 - ofx file import tries to match online_id against ACCTID[space]ACCTKEY even when ACCTKEY is
empty

Alters the gnucash account matching code to search a second time if
the original search fails and the account ID has a trailing space. The second
search tries with the trailing space removed.
