Certain autosave branch names crash the ui

[olevski]

A user reported the following:

Good morning Renku team, since yesterday I'm having some problems starting a new session on Renku on one project: a warning message tells me that there is no image available but whenever I want to choose a specific commit, the page goes blank. If I don't try to choose a commit, the page is stuck at 'checking sessions status'. I have tried: to load a session from an other browser restarting a new image build with a new commit logout, login Maybe related: yesterday I had this problem for any project (from my namespace and from 'omnibenchmark') but it disappeared after some time (except this one project). Any idea what is the problem and how I could solve it ?

Here is what their browser console looks like:

The problem was resolved after the user deleted the autosave branch. The name of the branch was like this renku/autosave/fname.lname@uzh.ch/master/08007f6/134cf16. I removed the actual first and last name for privacy but there was nothing weird there.

I will check how the notebook service handles this branch. But I think it should be fine because the format is as expected and the name does not even have special character or anything else that could cause trouble.

This was the project where this problem occurred: https://renkulab.io/projects/omnibenchmark/omni_clustering/filter-expression

I can replicate the issue by cloning the project, then going to gitlab and creating a new autosave branch from master with the same name as above except with my user's email.

This is the response from the notebooks for the austoaves:

{
    "autosaves": [{
        "branch": "master",
        "commit": "08007f6",
