"Show Logs", displaying environment build logs, does not work with the current tljh version (JupyterHub 4).
Discussion
The feature fails because the _xsrf token, required since JupyterHub 4, is missing from the request. The tljh-repo2docker's "Show Logs" does not use JHAPI when displaying the terminal, which means we need to handle the XSRF token explicitly.
