viewer: avoid high cpu usage when selecting part with no filter

When selecting a message part that has no filter configured, aerc uses
very high CPU.

This is due to a recursive UI invalidation. PartViewer.Draw() calls
newNoFilterConfigured which calls ui.Grid.AddChild which in turn calls
ui.Invalidate() which causes the whole UI to be redrawn.

Call newNoFilterConfigured only once when creating a new part viewer
(only when there is no filter command).
