Tests Run in Jenkins

Android library projects cannot be tested directly. In order to successfully have Jenkins run tests for TouchDB-Android, it needs a Standard Android Application project as the targetPackage in the instrumentation attribute. This commit moves the activities out of the testing app out into a separate app (com.couchbase.touchdb.testapp) and updates the test app (com.couchbase.touchdb.testapp.test) to match convention.
