Describe the bug
I noticed that if I switch from Closed Loop to Open Loop, the insulin that was delivered during closed loop is no longer included in any of the IOB.

I had used Loop for awhile and then had been trying O5. I decided to give Loop 3 (with patches) a go. Last night, after installing I was running everything in open loop with 0 IOB. After a while, my sugar was high so I decided to close the loop and let the system start giving corrections. It rose my basal to 2.5 units for 20 minutes. It was saying my IOB was around 1. I then switched back to open loop as I'm still trying to iron out my settings since it's been awhile. I then noticed that the IOB went back to near 0. The graphs didn't show any of the insulin it had given me. But it was still logged in my event details and on my pump.

To Reproduce
Steps to reproduce the behavior: Try this:

1. Open loop for awhile.
2. Close loop and be sure it's giving you extra insulin
3. After like 15-20 minutes "open" loop again.
4. See if it correctly includes the insulin it delivered in the IOB. (May take a cycle to calculate)

Expected behavior
I expected that Loop would still maintain any IOB it gave me while closed, even if I open it back up - as that's how the app worked in the past.
