refactor(communities): use ImportingHistoryArchiveMessages signal for

banner

@John-44 requested that we show the banner only for when messages are indeed
imported into the database, not necessarily already when the torrent data is being downloaded.

This commit ensures Desktop processes the newly introduced
`ImportingHistoryArchiveMessages` signal to render the banner introduced
in d5db1e6356
