Refreshing Detail view deselects selection from Master list on iPad

[ZachOrr]

Describe the bug
On iPad, after selecting an event/team/etc. from the master list on the left-hand side, when the detail view on the right-hand side refreshes, the selection from the master list is deselected.

To Reproduce
Steps to reproduce the behavior:

1. Go to the Events tab (or Events list)
2. Click on an Event
3. Pull to refresh on the Event
4. Notice the selection in the list is now deselected

Expected behavior
The selection in the Master list should stay highlighted, regardless of the Detail refreshing.

Interestingly, this happens in the Events/Teams list but not in the myTBA tab. My guess is that the refresh is updating our backing model and our fetched results controller for the master list is reloading, which means the underlying data is invalidated and our selection gets deselected. The myTBA list works slightly differently where that refresh doesn't reload the underlying data, since it's backed by myTBA models and not Event/Team models.
