fix(client): prevent session issues for uppercase namespaces

[lorenzo-cavazzi]

Projects with uppercase namespaces were messing up sessions, resulting in:

• Wrong feedback on the sessions dropdown menu in both the header and the dashboard (in the screenshot, all projects are paused but the last one shows "Start" instead of "Resume").
• Missing sessions in the project's session tab.

This PR fixes it (in the screenshot, left is on "dev" and right is on the current PR).

P.S: making a namespace uppercase requires some effort; the easiest way is to go to GitLab, create a new group, and manually update the group namespace to make it uppercase.
Here is a test project: https://gitlab.dev.renku.ch/uppercase-group/UPPER/uppercase-namespace

Some suggested changes:

In client/src/components/list/ListBarSessions.tsx - L255, you can also add the session name:

<SessionButton fullPath={fullPath} gitUrl={gitUrl} runningSessionName={notebook.name} />
