shell: Destroy a previous input panel animation when showing it again
It is possible that an input panel will be shown quickly, hidden and
shown again, before the animation for the first appeareance finished.
In that case, another animation would be created and the effect of the
two combined could cause the panel to not appear in the screen.
This patch fixes this by keeping a reference to the previous animation
and deleting it when a new one is created.
