Test hangs and timeout on setUp: GoogleInstumentation (ActivityFinisher) leaks activities between tests

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create Test1 which goes from Activity A to Activity B to Activity C
2. Create Test 2 which does the same
3. Check the Activity Stack when Test 1 ends

What is the expected output? What do you see instead?
Test2 will start and Activity B is still on the Stack

What version of the product are you using? On what operating system?
1.1

Please provide any additional information below.
This can result in test hanging between each other and failing with a timeout 
on startActivitySync.

A fix is proposed and pushed
