[Scip] objdelta infinity

[Jacob Spönemann]

  Hello Gerald,

thank you for answering my request.

@SCIP-version: I'm using SCIP-1.2.0.

@lowerbound(*): I neither change the lowerbound of the current node, nor 
*lowerbound pointer, unless there some side-effects of functions I use.

@backtrace: Attached.

Best regards,

Jacob
