Several tests because non-functional after git removal
and python 3.6 code update. This patchset will ensure
that these tests function with current ranger codebase.
Also removes erroneous use of rand_region functionality
when testing flavors, flavor testing should always use
real ranger regions, otherwise database will require
manual purging of flavor after it goes into error status.
