Unregister idling resource after each test.

[GoogleCodeExporter]

Here what my test cases looks like:

public class TestPager extends ActivityInstrumentationTestCase2<TestActivity> {

    public void setup() {
         Espresso.registerIdlingResources(new PageIdlingResource());
    }

    public void testA() {
    }

    public void testB() {
    }

}

----

The problem comes from the fact that setup() is called twice during the test 
run: once before testA() and once before testB(). As such, Espresso instanciate 
and keeps the IdlingResource of each test. Let's say I have 20 tests. After 20 
tests I have 20 PageIdlingResource registered. 

So we need a way to unregister any IdlingResource when a test is complete. 
Either automatically, or in the tearDown() method.

In the next release, Espresso will ignore registration of resources with the 
same name. In the future, we may provide a de-registration method.

Espresso 1.1 will ignore registration requests for duplicate resources.
