Remove tag feature doesn't work

[skysb]

In the build pipeline, I have added the step of workitem updater in the following manner:

- task: WorkItemUpdater@2
  displayName: 'Update workitems to release'
  inputs:
    workitemsSource: "Build"
    workItemType: Task
    workitemLimit: "500"
    workItemState: 'Ready to Test'
    workItemCurrentState: 'Active,New,Review'
    removeTags: 'PR Merged'
    updateAssignedTo: Always
    updateAssignedToWith: Unassigned

The items attached to the build should have the PR Merged tag removed but it didnt.

This is the logs from the build:

2021-10-08T12:43:06.3891016Z Found WorkItem: 13019
2021-10-08T12:43:06.3892152Z Updating WorkItem 13019
2021-10-08T12:43:06.3893207Z Patch: /fields/System.State Ready to Test
2021-10-08T12:43:06.3893550Z Patch: /fields/System.AssignedTo undefined
2021-10-08T12:43:06.3894363Z Patch: /fields/System.Tags 
2021-10-08T12:43:06.5585492Z WorkItem 13019 updated

and here is a screenshot of the item with the tag still there:

Is there anything missing or done incorrectly?

This should work again with the latest version. It was fixed in #87
