In a recent commit workload versions were changed to match their APK versions.
This commit adds the old versions to the allowed versions and automatically
maps them onto the new values.
After running the benchmark, when collecting the output files the execution
fails because the split('\n') call, used for creating a list of output files,
returns an empty string as last element. The empty string makes the pull command
fail because file '' doesn't exist on the target device.
