LGTM! What is a bit worrisome here is that the tests will always run a different version of azure-core than "normal" installations. As the differences between those versions should not be dramatic and are restricted to azureformrecognizer, this is OK.
Anyways, if we encounter any problems with that, pinning msrest<0.7 would be an alternative solution to this change.

Great! I did the same reasoning. We should also verify if the pin to that specific beta of azure-form-recognizer if really necessary, that can solve a lot of problems in the future.
