There is a lot of boilerplate testing code that performs common
AddonManager operations. Some common operations used for testing
Experiments have been refactored into a testing-only JSM that lives as
part of the Add-ons Manager.
The experiments service insists on being in control of experiments.
Before, it wasn't being as assertive as it needed to be: other browser
components could install experiments behind its back. This patch
reasserts the experiments service as king of experiments add-on
management.

Before this patch, experiment add-ons may have existed in the Addons
Manager without the Experiments service knowing about them. This detects
these unknown add-ons and uninstalls them. See the in-line comment on
the rationale behind this decision.
The added unit test fails without the Experiments.jsm change.
* no need to pass an addon/experiment ID to .disableExperiment()
* fix multiple-logging when multiple Experiments() objects are created as in tests
* ensures that all dirty writes actually get written
