RUM-6570: Fix Rum integration test verifyViewEventsOnSwipe

[ambushwork]

What does this PR do?

There are two integration tests failing for very long time,

• ConsentPendingGrantedFragmentTrackingTest.verifyViewEventsOnSwipe

• ConsentGrantedFragmentTrackingTest.verifyViewEventsOnSwipe

This is due to the action we perform on the test activity never works:

onView(ViewMatchers.withId(R.id.tab_layout)).perform(ViewActions.swipeLeft())

It's a known issue of Espresso that swipe is not working on a view pager, so we can never perform the action that we want,

to fix it, I added two buttons on the layout to go to next or last page, and replace the swipe action by clicking the buttons.

Another issue is that in integration test we need to override the importance of the process otherwise we don't receive the event of application start
