AttributeError: 'ThreadedDict' object has no attribute 'userrole'

Reproduce steps:

1. Install CeTune master
2. Install CeTune webui
3. Add user: python user_Management.py -o add --user_name admin --passwd 123456 --role admin
4. Run benchmark.

There's error in "python webui.py" runtime log:

Actually, when running python user_Management.py -o list there is admin user listed.
