[FIX] account: don't recompute ending balance of last statement

Previously a task was created to prevent holes between bank statement,
meaning that starting balance should always be the same as previous
ending balance. The goal was that during synchronization or imports,
we could add statement lines in previous statement and not have to
recompute manually the full chain of starting and ending balance of
next statements entries. This works fine with online synchronization
as we always write after creating the statements the balance
of the account on the latest statements to detect missing stmts,
however if we create stmts by hand, it is possible that we have the
following case:

Statement on 10 January with a starting and ending balance of 100 and 200
respectively. We are missing 2 statements with a line of 50 each before that
date. So we create the first missing statement at date: 8 January with a
starting balance 0 and ending balance 50, this will recompute the starting
and ending balance of next statement and overwrite the values to 50 and 150
(starting and ending balance respectively). At that time the system will say
that everything is normal but we are still missing a stmt and we are not seeing
it.

The way to fix this is by not touching the ending balance of the last
stmt entry during the computation, that way we can still detect that there is
an error and that 50€ are still missing.
