[PATCH 0/2] MR2736: Draft: Reset presentation flags when session_clear_presentation is called.

[Santino Mazza (＠tati1454)]

This prevents hangs when a program sets a new topology after stopping the current
topology, because if we don't reset the flags to 0 the session will not subscribe
to the events of the new topology sources.
