    fix reconcile dialog always showing ending balance of zero
    
    The reconcile account dialog always displays a value of 0.00 as the
    Ending Balance, regardless of account and statement date.
    This is caused by function xaccAccountGetReconcilePostponeBalance
    returning the wrong value, returning TRUE when it should return FALSE,
    and setting balance to the default {0,1}.
    
    The code uses bal.denom!=0 as an indicator that a valid balance was
    received in variable v. However, bal is initialized to {0,1}
    making the test always true even when we didn't receive a valid
    value in variable v.
    Thus, this function returns TRUE with *balance={0,1} when no valid
    balance was found in "reconcile-info/postpone/balance".
    
    This patch fixes the function to return FALSE if v doesn't hold
    a valid value or if bal.denom is set to 0.
