Revert 'Fix "launchOrFocus" behavior for Atom'

Revert 4f7a69f. While that commit did
improve things for Atom, it made things worse for other apps like Chrome
and Finder. With those apps, if the app is open but no windows exist,
the changes in 4f7a69f would focus the
app but wouldn't display a window. Chrome with no window isn't
particularly useful. 😬
