Provide "access" to tasks for UI tests.

Context

tasks-app is a content app, tho it is added to the group /modules/ui-admincentral/config/appLauncherLayout/hiddenApps, hence it cannot be opened via find bar.

There is an always available "box" on the Uadmin with a link to open the app and the number of tasks.

Required functions, methods:

• Open the tasks app (which I expect to work as every content app once it is opened)

• Providing the number of the task counter*

*) The task counter displays the combined total of new tasks and tasks assigned to the current user.
