In order to workaround an bug in applaunch running on android N, all of the
workloads have been updated to the latest gradle build system, the timeout in
the baseclass has been changed from a TimeUnit to a regualr long and a
duplicately declared parameter bundle has been removed.
Each workload has be modfied to remove the old manual paremeter conversion
and instead to retrieve the desired type from the parameter bundle directly.
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.
