    [qif-to-gnc] Bug 796579 - Cannot go forward with empty duplicates screen
    
    better fix for bug 796579.
    
    far-acct-info is a record with acct-info
    far-acct-name is a string
    far-acct      is a gnucash account object
    
    (default-unspec-acct) always returns a string "Unspecified".
    
    983c7ce0b was trying to find, from qif-memo-map the mapping for
    "Unspecified" which isn't typically part of qif-memo-map. Therefore
    far-acct-info would remain #f and fail the qif-map-entry:gnc-name.
    
    Better fix: if far-acct-info cannot be derived, use unspecified account.
