DEV-2835 Cleanup routes and unused components

Quite a lot of routes are never routed within the app. Quite a lot of components are unused and/or not implemented

Unused routes:

1. "lists" & "ontology" → HintComponent

   • get rid of routes to HintComponent
   • clean up HintComponent (remove unused "lists" and "ontology")

2. "dashboard"

• get rid of route
• fix its "implementation" (user component & globals.usernav)

Unused and not implemented components which have a route:

3. clean up SettingsComponent from Appglobal.projectNav

• do NOT get rid of SettingsComponent
  • get rid of Appglobal.projectNav → only one menuItem used by the whole app and this is in the very SettingsComponent. This should should therefore be defined locally in the Settingscomponent
  • get rid of Appglobal.projectNav and "this.navigation" in ProjectComponent hence not used at all

4. Remove PermissionComponent and AddGroupComponent

The PermissionComponent and its child AddGroupComponent are not yet implemented and not routed anywhere except the Permissionscomponent itself by the exact Url via routing.module

5. Clean up UserComponent and implement route constants

6. Remove unused CollectionListComponent

   The component is not routed, not used and not implemented

7. Remove GroupsComponent and it child GroupsListComponent
   Both components are not yet implemented, not routed and not used in any template
