Use actual number of packages rather than getCount()

The ResolverActivity method getCount() returns the number of
entries below the default entry, not the total number of entries.
But the onCreate() method expected the getCount() method to
return the total number of entries. This change provides the total
to onCreate().

Fixes bug 16800358.
