[Scip] Heuristic parameters not recognized

[michael.winkler at zib.de]

Hi,

Ambros is right, you need to add "/freq" but still it should be

"heuristics/oneopt/freq = -1" or
"heuristics/simplerounding/freq = -1"

"heuristics/oneopt/simplerounding/" should not exist, also it should not
be printed when disabling all heuristics. Can you check your output again.

Best, Micha
