[Cbc] CoinError when using "-preprocess strategy"

[John Forrest]

Patrik,

The fix is not to use -preprocess strategy :-)

Since changes to Cbc to make it easier to use command line code as a 
function, the "strategy" options have not been much tested.

I have fixed in stable.  CbcModel.cpp change 2002.
