[Marsha BBB] Show the teacher dashboard after sharing a LTI link from the site to Open edX

[NamFra]

Bug Report

Problematic Behavior When you share an LTI link from https://marsha.education to Open edX (after the portability request) for a classroom in BBB, you will only be able to see the student view and the classroom must be started on the standalone site.

Expected behavior/code You expect to be able to launch it directly in the Studio of the LMS.

Otherwise, the teacher/student role detection works correctly in the LTIContext.

Steps to Reproduce

1. Create a BBB classroom on the standalone site.
2. Copy the LTI link.
3. Go to a course in the Open edX Studio.
4. Request playlist portability and accept it on the site, if it hasn't been done already.
5. Observe that the student view appears instead of the teacher dashboard.

Environment

• Marsha version: beta.15 (staging)
• Plateform: Open edX Ironwood (staging d2rp)
