Patch the TOTAL execution count widget b/c it was incorrect

- can't have <li> elements outside of <ul>
- spacing between label & number was missing - inconsistent with
  the labels above
- point the URL explicitly to the current TR instead of using '#'

Note: when using '#' for the URL and filtering by status the
resulting URL was
'/runs/123/?status_id=x#', now it is '/runs/123/'!
