Fix partial redraw during filament autoload

Browse Source 
If the printer was already being pre-heated but didn't reach the target
temperature yet and a new filament is being inserted, the LCD used to
display a "Preheating to load" message to block the loading until the
extruder is hot.

This message is currently missing, and the ">Cancel" option doesn't
display immediately either, depending on the extruder height.

This PR fixes this behavior, which was broken during an earlier update.

We now force-update LCD updates during the first (and _only_) time the
screen is setup, and push all messages _before_ the carriage is
eventually raised, so that ">Cancel" is shown immediately as well.
