[Scip] scip 3.1.1 using presolve aggressive programmatically

[sct]

Dear scip,

I was using scip programmatically & have set presolve to aggressive. 
However, I noticed that the settings was not executed. (There was no 
printout to console when silent flag was set to 0 & the number of 
presolve rounds was exactly like the default).

I have used the below in my program.

-----
     SCIP_CALL( SCIPcreate(&scip) );
     SCIP_CALL( SCIPincludeEventHdlrBestsol(scip) );
     SCIP_CALL( SCIPincludeDefaultPlugins(scip) );

...

     SCIP_CALL(SCIPsetHeuristics(scip, SCIP_PARAMSETTING_AGGRESSIVE, 0));
     SCIP_CALL(SCIPsetPresolving(scip, SCIP_PARAMSETTING_AGGRESSIVE, 
0)); - no printout to console
     SCIP_CALL(SCIPsetSeparating(scip, SCIP_PARAMSETTING_OFF, 0));
