fix(android): fix global header/footer title in ListView

[m1ga]

Issue

I don't think it is widely used but you can add a headerTitle/footerTitle in the ListView instead of the ListSection. When I was working on the test suite PR (#14158) I saw that that test was failing.

12.6.1.GA:

The issue is that the content section has no view (as it is just the global headerTitle, so it doesn't have items) and that messes up the constraints. The "global header view" is visible as it creates a view.

Fix

As I don't know at this point which kind of headerTitle (section or global) I just check if there are views inside the content section. If not I create an empty view and add it. That will keep the constraints working
