Add a recycler view test method scrolls to a position (#31)

* Add a recycler view test method scrolls to a position * Add more fruits to have a really long RecyclerView * Make the rows larger to disturb Espresso * Add tests to check clicks and scrolls in the stard of the list, the middle and the end * Introduce Recycler.scrollTo in the README.md * Add Recycler.scrollTo to the test that checks the content that we add to the README * Remove unneeded imports
