Original change's description:
> [3P blocking] Fix tests accessing the ModuleDatabase on the UI thread
>
> The ModuleDatabase was moved to its own sequence but both the
> IncompatibleApplicationsBrowserTest and ThirdPartyBlockingBrowserTest
> test fixtures were not updated.
>
> This CL moves the accesses to the ModuleDatabase instance to the right
> sequence.
>
> Also added an override for the OutOfProcessQuarantine feature to allow
> local testing. This was not an issue on the bots because they respect
> the fieldtrial_testing_config.json file.
