[FIX] account: auto-balance opening entry
[FIX] account: auto-balance opening entry

If the opening entry is balanced, the auto-balance line is unlinked.
However, before unlinking we test if it is balanced, which it is not. A
solution is removing the line from the move and it will be unlinked
automatically.
