No simple way to test "Print" action on Activity Services (Share) menu

PrintControllerTestCase tests are unconditionally disabled. I looked into
enabling them by rewriting them using XCUITest. It turned out that
XCUITestElements do not give access to the actions on the Activity
Services menu.

Deleting tests since they are not serving any purpose.
