Bug 19681: Correct result count formatting

This simply passes the missing information to the template.

Test plan:
0) Apply patch
1) Go to Tools > Label creator > New > Label batch
2) Press 'Add items'
3) Do a search that will return few items
4) The result count will read "Results 1 through X of X"
