Fix AllAppsSearchPlugin icon redrawing without special-casing.

Preventing icon animations in deep shortcuts fixed the icon redrawing issue in the all apps search page, however other icons could still be redrawn, yet could not be special-cased without removing icon update animations altogether. Added logic to only animate icon updates outside of the all apps search page.
