Tweak resultsdb scenario not to include VERSION or TEST
For resultsdb we decided test name + scenario should be taken
together, so including the test name in the scenario is not
necessary. threebean pointed out that including VERSION is
awkward for greenwave use (and anything that wants to specify
a list of possible / expected scenarios), and not necessary for
Fedora results as the BUILD and/or ITEM should always identify
the release version...
