Fix page_entries_info when array is empty

[monfresh]

This fixes #1013

Previously, the code was not taking into account that you can call paginate_array with an empty array, while passing in the total_count.

This fix checks to see if the records are empty or not. If they are, then the to variable uses a different calculation.
