test(store): assert the whole reminder, not a bare minute count

First on-device run of the instrumented suite against the branch tip: 66
tests, one failure, and it was the test that was wrong.

`alarmsRoundTripAndReplaceRatherThanAccumulate` asserted
`source.alarms()[id] == 30`. The seam stopped returning a bare `Int` in
fcee1d1, when collapsing an alarm to a minute count turned out to be what
fired an imported START-referenced reminder off DUE — `alarms()` has returned
`Map<Long, TaskReminder>` ever since. The production value was correct
(`TaskReminder(minutesBefore=30, fromStart=false)`); only the expectation was
left behind.

It compiled the whole time because Truth's `isEqualTo` takes `Any?`, so an
`Int` compared against a `TaskReminder?` is a perfectly legal call that can
only ever be false. Nothing short of running it would have found this, which
is the argument for the ROADMAP item that asked for the run.

Now asserts the whole value, so the reference is part of the contract rather
than something the test is free to ignore.

66/66 green after the fix.
