Issue: [4.1 Beta 1] Admin cp: The wiki currently appears as disabled because a deferred task has failed. Bad URLs and styling tweak (use block-rowMessage)

In the admin cp at the path admin.php?options/groups/vw_server_settings/, the following phrase appears beneath the vw_enabled checkbox:
1) "Server Error Logs" and "retry the failed task" are bad hyperlinks:

• Server Error Logs: %7B$logUrl%7D
  
  • The requested page could not be found. (Code: invalid_route, controller: -, action: -)
• retry the failed task: admin.php?wiki/counter&do=update&counter=unhold
  
  • The requested page could not be found. (Code: invalid_action, controller: vw\vw\Admin\Controller\Wiki, action: Counter)

2) The CSS styling is a bit random with "!!!" and all red text. Why not change this span to use XF2 styling? It would look more consistent and remove the need for some custom CSS classes. For example,
find
replace with

Also, despite the error message suggestion, nothing was logged in the server error logs at path admin.php?logs/server-errors/. The vw_defer table reveals a number of defer=totals and defer=prefixkey rows, both with hold=1 and complete=0. After some time (several minutes or more) later, the wiki did eventually re-enable itself.
