[GNC] some of my reconciliations in 3.9 are completely bonkers

[Christopher Lam]

This is due to https://bugs.gnucash.org/show_bug.cgi?id=797640

This change modifies the reconciliation starting balance calculator from
Account->reconciled_balance to account->reconciled_balance on statement
date.

The reasoning for this change is with the observation:

(A) if reconciliation is performed from a statement dated 31/01/2019, the
starting balance calculator should ignore transactions posted later than
31/01/2019.

(B) subsequent work https://github.com/Gnucash/gnucash/pull/667 aims to
store past reconciliation ending balances and statement date. As a result
we can re-reconcile any past statement.

(C) subsequent work will allow a sanity-check type report (illustrated in
above PR)  which will compare account reconciled balances at previous
statement dates, and highlight any discrepancy.

There have been previous feature requests to store and retrieve reconciled
balances and reconciliation dates, and I believe it's possible and
reasonable.

Having explained the rationale, the reasoning (A) may be incorrect --
please file in bug 797640 how/why starting_balance should include
transactions posted after statement date. If reasoning (A) is invalid then
we will need to revert the change, which means (B) and (C) above cannot
happen.
