help.test needs a cleanup

The existing test assumes that every enabled module implements hook_help(), and also uses assertions that could be influenced by external settings (site name, theme, etc).

The help module doesn't provide much besides the implementation of hook_help, and that hook has very loose requirements. The only way to figure out if a module will display help on a certain page is to call its help hook and see if something is returned. There is no guarantee that a module implementing hook_help will display anything on any page.

Here's a patch that works, but I'm still not satisfied with the approach. I'm working on a dummy module whose only purpose would be to test hooks, but that's a different issue.

Change component is relation to http://drupal.org/node/253744.

The issues were stated here, but never fixed: http://drupal.org/node/242475.

help.test is rewritten, no comment out assertions left
