When they are created without any roommates, they should become inactive reminders until roommates are added to the reminder.

• [ ] reminder card should show that they are inactive as well
• [ ] need a way to activate the reminder from room
• [ ] modify reminder card validation to allow creation without any roommates

@MarcusTan, assigning you since I think the modification of the validation is the biggest part and you would understand it best.

Going to move to 0.2, because not priority.
