A "please rate me" dialog occasionally pops but when returning to the
initial screen (when re-running the test). The check to dismiss it
wasn't being done at the right time, so it was still preventing
mutli-times execution. This commit resolves that issue.
"times" parameter didn't work properly for version 5 because an extra
back button press was required due to UI changes from previous versions.
This commit adds the button press.
