Membership status incorrectly calculated under some dates

Pete has identified a set of dates that fail to generate a membership status. Not sure if this is new to the 5-year fix or this is finally a way to replicate the mysterious intermittant bug. Test that demonstrates is

/**

• Test that correct end date is calculated for fixed multi year memberships and start date is not changed.
  *
• In this set our start date is after the start day and after the rollover day so we do get an extra year
• and we end one day before the rollover day. Start day is 1 April so we end on 31 March
• and we add on 5 years we are after the rollover day - so we calculate 31 March 2020
