luci-app-attendedsysupgrade: fix empty array condition

Browse source 
In JavaScript (other than in Python) an empty array is considered `true`
within if statements. Fix this by checking for the array length rather
than its existence.

This fixes the issue of an empty dropdown menu in case the user is
running the latest release.
