Update dependencies

[MGaetan89]

I've updated the dependencies of the project to the latest version:

• Android Gradle Plugin 4.2.1
• AndroidX Annotation 1.2.0
• AndroidX AppComapt 1.3.0
• AndroidX Core 1.5.0
• AndroidX Fragment 1.3.5
• AndroidX RecyclerView 1.2.1
• AndroidX Test 1.3.0
• AndroidX Test Espresso 3.3.0
• AndroidX Test Ext 1.1.2
• jUnit 4.13.2

Most changes come from the deprecation of ActivityTestRule in AndroidX Test. I tried to adapt the code to keep the changes to a minimum.

For the changes to the tests for deprecation of ActivityTestRule in AndroidX tests mostly you have replaced a check via an API method to a test for does it exist in the Layout hierarchy.

i.e.

 RelativeLayout cornerView = (RelativeLayout) tableView.getAdapter().getCornerView();
        Assert.assertNotNull(cornerView);
        // Check the corner view is visible
        Assert.assertEquals(View.VISIBLE, cornerView.getVisibility());

with

 onView(withId(R.id.corner_view))
                .check(matches(not(doesNotExist())))
                .check(matches(withEffectiveVisibility(Visibility.VISIBLE)));

So not checking the exact same thing, but I'm undecided whether this is OK or not. I guess the intent of the check was to check it was drawn and not to check the getCornerView method.
BUT the .check(matches(not(doesNotExist()))) part is redundant as the onView part will fail to find it in the layout if it did not exist

I note that CornerViewTest.java and SimpleActivityTest.java tests did not get converted to the onView methodology instead of the using Api methods for consistency.

Hey, thanks for having a look.

I've started to update my changes. I'll update my PR tomorrow.
