Revert "shell: Make sure we don't focus the icon view when starting"

This reverts commit 8e0f4e7be0e532d33105962e7f49d0e47d29ddfb - there's
a better fix in the next commit.
shell: Make sure we don't start with a selected icon

If focus ends up in the icon view we get an ugly selection so avoid
that at least initially.
