fix: make android mocha tests run again

[m1ga]

I was wondering why the Android mocha tests weren't running anymore. Turns out: the generated tiapp.xml was invalid. There was a missing > and it had two <application> (we have a default one in the template now) nodes.

Fixing some tests:

• tls 1.3 url was not working. Using a different one
• redirect url was blocked, using a different one
• one test was throwing a "getText() of null" error for the label so I've added a null check
• headerTitle/footerTitle is not working (even with 12.5.0) so disabling that for the moment - Fixed in fix(android): fix global header/footer title in ListView #14160
• added another density image for the textfield padding test

Interesting point:
tableView.deleteRow(tableView.sections[0].rows[2]); is not working in the emulator but on a device it is working fine 🤷 That's one test that is still failing but couldn't fix it yet.
