ImageScSearcher: do not load remote icons

Firstly, this logic introduces an undesirable package dependency on
the org.scijava.ui.swing.search package, which is AWT/Swing-specific.

Secondly, loading the remote icons is expensive, and makes
search results appear (especially in napari-imagej) too slowly.
