ui-manchette: fix manchette toolbar not fixed bottom

The PR #728 changed the height of the manchette from a min height to a fixed one.
It introduced a bug where, when having a long list of waypoint, when scrolling bottom, the manchette toolbar wasn't stick to the bottom anymore.
Fix this issue by giving back a min height to the manchette while still keeping its dynamic value introduced in PR #728.
