[Scip] Changing time limit during solving make SCIP freeze

[Aurélien Questel]

A small precision : when the time limit is reached, the solving process may stop and display
the different statistics (#nodes, best sol value, etc…) 
but then my program freezes and the following procedures of my pricer aren't reached.
So I know for sure that the issue appends between the stop instruction and the termination of a scip instance
