Do not assume order of report list elements

Do not assume order of report list elements

This fixes the test_report_multiple_services unit test that breaks with a
randomized PYTHONHASHSEED (see the bug report).

The test assumed that the report list from self.driver.report_status() had
elements in a particular order. Found with PYTHONHASHSEED=2455351445.

The fix refactors the test case to handle an unsorted report list by
sorting it before checking equality.

Partial-bug: #1348818

Note: There are several other unrelated unit tests that also break with a
randomized PYTHONHASHSEED, but they are not addressed here. They will be
addressed in separate patches.
