[FIX] account: accurate amount total due with partial reconcile

This is related to rev. db98434e85be8ae0dfdb580a263704e3bac454e2

rev. abe5c803a0e36f18aec4cc56abc289f66329a749 forgot some partial reconciliations when the date domain was other than BETWEEN (for instance, <= stop date or >= start date, alone, not between)
Besides, the rev. abe5c803a0e36f18aec4cc56abc289f66329a749 did not care about account move being posted or not.

rev. db98434e85be8ae0dfdb580a263704e3bac454e2 took several times the same partially reconciled moves lines
