az extension datafactory 0.7.0 is broken for working with pipelines

If you install the latest az datafactory extension (0.7.0), then run az datafactory pipeline list --factoryname blah --resource-group rg-blah throws an internal error after 10+ seconds. If you run with --debug, you can see it does pull down the json, but errors out

If you uninstall it, then install az extension add --name datafactory --version 0.6.0

it works.

#### Document Details

az datafactory pipeline list --factory-name blah --resource-group rg-blah
(InternalError) Internal error has occurred.
Code: InternalError
Message: Internal error has occurred.

all other az datafactory pipeline stuff also fails.

If you run same command but with --debug, you can see can see it actually fetch the json results, but then has a 'This request has no body several times, and a few {"error":{"code":"InternalError","message":"Internal error has occurred.","target":null,"details":null}} errors.

Rolling back to 0.6.0, it works.
az extension remove --name datafactory
az extension add --name datafactory --version 0.6.0
az datafactory pipeline list --factory-name blah --resource-group rg-blah
gives me json info about the pipelines.

0.7.0 is broken for datafactory pipeline commands. all other datafactory resources work (trigger, dataset, etc.)
