Remove the third line in the clear data dialog warning about clearing
data for installed apps, and instead warn about that in the main label
on the dialog.

This also changes the main label to only dynamically warn about
installed apps data, depending on whether or not there is an
associated installed app, and whether a SiteGroup has more
than one installed app.
