Parsing errors while DTFx processes the messages from queue in latest version of DurableTask.AzureStorage 2.0.0-rc.2.

Hii,
We started consuming the 2.0.0-rc.2 version of DurableTask.AzureStorage nuget as previous versions contain reference of the deprecated versions of "WindowsAzure.Storage".

After consuming the nuget we deployed in the ECY Canary region for testing. After deployment, we started encountering the Json parsing issues while dtfx processes the queue messages. "Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: e. Path '', line 0, position 0.".

Full exception message with stack trace:

```
An error occurred while processing messages on springboot-workitems: Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: e. Path '', line 0, position 0.

```

We started encountering these issues after updating to the "2.0.0-rc.2", prior to that we didn't observe these issues. We observed that a periodic workflow which we run every 5 mins is not getting executed but there are few successful executions of other workflows as well.

Let me know if you need anything further to debug this issue.
