crash in CallAdapter

Describe your environment

Please specify the following:

• OS: Linux
• Jami version: client-qt commit ID 252bc848

Steps to reproduce

• Can you reproduce the bug: only once so far
• Steps:

1. Call a RDV point
2. Maximize any participant video

• Actual result: crash
• Expected result: no crash

Additional information

Quick investigation shows that the index provided to CallAdapter::onParticipantUpdated() method is out of range:

ASSERT failure in QList::operator[]: "index out of range", file /opt/Qt/6.2.3/gcc_64/include/QtCore/qlist.h, line 412

I also noticed that the RDV point continued to display a participant that had previously left the conf (in fact, the participant crashed, so maybe the conf did not update correctly)
