now" link

 The plugins list page gracefully handles the case when the package field
 is empty in the update_themes transient response by showing "Automatic
 update is unavailable for this plugin/theme." This is also shown correctly
 in Network Themes and when you open the theme details popover on a single
 site.

 However in the themes.php grid it still shows the "update now" link which
 when you click will eventually show a "Update Failed: Update package not
 available." error. The grid needs to be adjusted to account for empty
 packages.

 I know it's an obscure error, but it may be encountered when premium
 plugins/themes hook into the update process and rely on the empty package
 functionality until authorization is granted by entering a key or logging
 in, etc.
