The command palette runs a picked command with no params. Export Assets
then failed with "no assets yet" (or, with assets collected, exported
to no folder), and Remove, Rename and Asset Export Settings failed or
did nothing. Run with no params from the palette, a menu or a shortcut,
these four commands now show the Asset Export panel, and leave it open
when it already shows, docked or floating. Calls with params are
unchanged.
