The singular delete-flash agrees with itself: "so it stays usable" (#1710)

deletionFlash() (added by #1567) pluralised the count, the noun, the
auxiliary and the pronoun, but left the verb fixed at "stay" — so the
singular branch, which is the common one, shipped "1 ticket was merged
into it ... so it stay usable".

The verb agrees with the pronoun, so it belongs in the same ternary:
"it stays" / "they stay". Nothing else about the message changes.
