Jenkins: rename rostest xml logs to match mission (#8616)
Jenkins: rename rostest xml logs to match mission (#8616)

two xml log files are generated for each rostest. they're named according to the launch file, which is reused for each mission test. currently subsequent tests overwrite the previous test's logs. this renames them after they're generated, appending the mission name to the end of the file name.
