Description
Accessing control panel URL on Weblogic throws IllegalStateException

Steps to reproduce/Testing done
Initial setup:

1. Deploy Liferay onto Weblogic (no other plugins are needed)
2. Set the following in portal-ext.properties to disable user personal pages
   layout.user.private.layouts.auto.create=false
   layout.user.private.layouts.enabled=false
   layout.user.private.layouts.modifiable=false
   layout.user.public.layouts.auto.create=false
   layout.user.public.layouts.enabled=false
   layout.user.public.layouts.modifiable=false

Role setup:

1. Login as a portal administrator
2. Navigate to Define Permissions for the User role
3. Select Control Panel > General Permissions
4. Under "General Permissions", give the "Go to Control Panel" permission
5. Save changes
6. Select Control Panel > Sites > Site
7. Under "General Permissions", give the "Access in Control Panel" permission
8. Save changes

User setup:

1. Create a user 'reviewer'

Steps to reproduce:

1. Sign in as the 'reviewer' user
2. Navigate to the control panel

Results:
Expectation is that there are no errors. Actual behavior is that Liferay throws an exception.

The issue is that we're sending a redirect inside of a JSP, so it will continue processing the remaining HTML (in particular, the RuntimeTag just below it).

<%
Map<String, List<Portlet>> categoriesMap = PortalUtil.getControlPanelCategoriesMap(request);

if (categoriesMap.size() == 1) {
    for (String curCategory : categoriesMap.keySet()) {
        List<Portlet> categoryPortlets = categoriesMap.get(curCategory);
        if (categoryPortlets.size() == 1) {
            Portlet firstPortlet = categoryPortlets.get(0);

            PortletURL redirectURL = PortalUtil.getSiteAdministrationURL(request, themeDisplay, firstPortlet.getPortletId());

            response.sendRedirect(redirectURL.toString());
        }
     }
}

request.setAttribute(WebKeys.CONTROL_PANEL_CATEGORIES_MAP, categoriesMap);
%>

Move logic to ServicePreAction, similar to work done in LPS-37846.
