Statistics don't open from CLI

Created by: WBTMagnum

On the command line there is the possibility to start dedicated hamster windows. E.g. help states: "overview / statistics / about: launch specific window".

When trying to open the statistics window, the following error is thrown:

$ hamster statistics
Traceback (most recent call last):
  File "/usr/bin/hamster", line 418, in <module>
    getattr(hamster_client, command)(*args.action_args)

Launching overview and about window works as expected. Is there even a statistics window in the revamped client? about window also stopped working now.

Just for the Record:

• Hamster was build from updated GIT repo today (revision a934effe).
• OS: Ubuntu 18.04.3 LTS
