jami-daemon crashes while performing tls handshake

Continuation from issue #573 (moved)

I compiled a lot of different versions of jami-daemon and found the first commit that introduced the tls issues. On this first broken commit the daemon didn't crash but couldn't perform a successful handshake.

Log from commit 2053afe9 but the regression likely stems from 6d4630bf:

[1636931798.072|  182|tls_session.cpp   :1059 ] [TLS] Start client session

...

Commit 2a676123 is first to crash jami-daemon with this error:
