Dealing with @bindable Being Non-Optional
/**
The idea is to be able to invoke `ReminderDetailsWrapper` (forgive the naming, it’s
the result of the organic growth of this thing) with either the ID of an object to edit,
or nil, in which case it will create a new one. In both cases, it has to create a new
`ModelContext` on which to make the changes, and it only saves if the user taps the
“Save” button.
Some of thie could be improved if things could be loaded in `init()`, but that gets
called far too often as SwiftUI rebuilds the view hierarchy.
