Issue Summary

• When a user is removed from a workspace, if the user was listed as a default reviewer for any repository, the default-reviewers endpoint still returns that user, even though they no longer have access to the workspace;

Steps to Reproduce

1. Add a user to your workspace;
2. Add the user as default reviewer for any repository;
3. Remove the user through the workspace's settings > User directory
4. Use the default-reviewers API endpoint for that repository;

Expected Results

• The user should not be listed as a default reviewer anymore;

Actual Results

• The user appears in the list of repository default reviewers through the API;
• Furthermore, if you try to edit a file and commit it through the UI, creating a Pull Request, the user will be added as a reviewer, causing an issue while trying to create the PR.

The below exception is thrown in the network tab of the Developer Panel:

{
    "type": "error",
    "error": {
        "message": "reviewers: John Doe is not a member of this workspace and cannot be added to this pull request",
        "fields": {
            "reviewers": [
                "John Doe is not a member of this workspace and cannot be added to this pull request"
            ]
        }
    }
}

Workaround

• Use the Delete Default Reviewer Endpoint to remove that user from the list of default reviewer;

  $ Curl -X DELETE -u <username>:<password> "https://api.bitbucket.org/2.0/repositories/<workspace>/<repo>/default-reviewers/%7B<UUID>%7D"
