    Fix 3 problems with the scheduled transactions calculations
    
    This fixes 3 bugs:
    - Set a monthly recurrence on the 10th with a start date on the 20th of this month.
    The editor correctly shows the next occurrence to be on the 10th of the following month.
    The schedule transaction summary dialog incorrectly shows the next occurrence to be on the 10th of this month
    (before the start date!)
    - Set a monthly recurrence on the 19th, with a start date on the 20th of this month. The editor's
    calendar marks incorrectly show the next occurrence to be on the 19th of this month (before the start date).
    - Set a monthly recurrence on the 18th, with a start date on the 20th and an end date on the 17 of the following
    month. The calendar should show no mark, but fails to erase the marks that were present.
