Fix 0003124: view_bugs: a reporter has the drop-down box of actions, but doesn't
have the checkboxes.

M view_all_inc.php

• Show combo-box of actions only if at least one checkbox was displayed. It has
  to be done this way, because in case of "All Projects" a different access check
  is done for each row.
