Closes #103

Short Description and Why It's Useful

• Improved flow to directly set primaryFacilityGroup on the facility instead of making it groupMember
• Changed the logic to use shopifyShopId as facilityGroupId instead of using productStoreName
• When updating primary store, first checking that whether a facilityGroup exists for the shopId, if not then creating a facilityGroup and them making primary store by calling updateFacility
• Updated the primary store feature on details and create facility flow
