fix(UpcomingDepartures): Show crossed out scheduled time for Delayed status

[joshlarson]

Scope

Asana Ticket: [SF/UD] 🐞 A status of "Delayed" should still show the crossed-out original time if scheduled and predicted times are more than a minute apart

Implementation

• Just some fiddling with function pattern-matching.

How to test

This is tricky to test. You could try to use LiveBook or IEx to find a prediction with a Delayed status:

2
|> Routes.Repo.by_type()
|> Enum.map(& &1.id)
|> Enum.flat_map(&Predictions.Repo.all(route: &1))
|> Enum.filter(&(&1.status == "Delayed"))

but Delayed-status predictions happen somewhat infrequently, so you could be waiting for a while.

...or you can hack Predictions.Repo.all/1 to make all predictions have the Delayed status by tacking on 👇 to the end (please don't commit this!):

|> Enum.map(fn %Predictions.Prediction{} = p ->
  %Predictions.Prediction{p | status: "Delayed"}
end)

(this is how I got the screenshots above - the 5:40 train is actually on time 😏)

Good luck!
