Compress testr results.html before fetching it
The synchronize command has testr_results.html.gz in the file list, but
we don't ever gzip it so it fails on fetch.
Make the "Check for testr directory" task actually check for
.testrepository and not for .stestr a second time.
The compression bug broke only for people using stestr. For people
using testr, the path bug meant they don't get html reports.
