Bug description
When uploading individual file using AzCopy, the activity log message doesn't include the file name in the log.

Steps to Reproduce

1. Turn on AzCopy in the Experimental menu
2. Under a regular storage account and blob container, try to upload an individual blob
3. When upload completes, take a look at the activity log

Expected Experience
I would expect to see the file name to be included in the activity log

Actual Experience
Only included directory information.

If AzCopy is turned off, we include the file name.
