When exporting to QIF all entries should be exported (currently, moneyGuru only export a transaction once, even if it figures in more than one account) because some financial app can't import those QIF correctly otherwise.
(from [a387397f2716]) [#353 state:fixed] Include all entries in QIF exports.
Previously, a transaction doing a transfer between asset/liability account would
only figure once in QIF exports but it would confuse some (lesser) financial
apps at import time.
