Sort Get parameters

Retrying the tests against 2.1.x - need to get green before this can land.

Makes perfect sense to me.

I think all this needs is an empty post-update hook to ensure caches are flushed, as if any formatter output is held in caches before this change, there will be hash mismatches until it's invalidated.

This can easily be back ported to 2.0.x, as 2.1.x isn't ready for prime time yet.

Err.. actually shouldn't the sorting happen in the ::getHash method?

Hi,

Thanks for the review. MR updated.

Also updating the version in the issue as the MR target branch had been updated.
