Room title overlaps the badge when tapping on the read marker banner

There was no issue before tapping on the banner.

See https://github.com/matrix-org/riot-ios-rageshakes/issues/623

Start by reproducing the room view shown in the linked screenshot, then tap the read marker banner and inspect the resulting title and badge layout. The payload names no source file or test; done means the room title no longer overlaps the badge after the banner is tapped, while preserving the normal pre-tap layout.
