Describtion
Two active overrides causes the loop to crash.
We had an active override for a lazy day and jumped into the car. While activating the car-override with the watch we'd two active overrides which leads to crash the loop:

        guard invalidOverrideIndices.isEmpty else {
            // Save the invalid event history for debugging.
            taintedEventLog = recentEvents

            // Wipe only conflicting overrides to retain as much history as possible.
            recentEvents.removeAll(at: invalidOverrideIndices)

            // Crash deliberately to notify something has gone wrong.
            preconditionFailure("No overrides should overlap.")
        }

We had no chance to get the loop running. The main view shows up for a second but disappears suddenly and no loop was in the active app list.

To Reproduce
Steps to reproduce the behavior:

1. Go to override menu on the phone
2. Click on an override to activate
3. Switch to a watch and activate an other override with an overlapping interval
4. Loop won't come up anymore

Expected behavior
When activating a new override from the watch deactivate the active one before.
