Turning off preprocessing to generate proof tree in all UNSAT queries

[aditi-goyal-257]

For my use case, I need a proof tree in all cases whenever the query is UNSAT. I wanted to remove cases where UNSAT was obtained in the preprocessing step itself. For this, I made the following changes:
1.set PREPROCESS_INPUT_QUERY to false in GlobalConfiguration.cpp
2.set PREPROCESSOR_ELIMINATE_VARIABLES to false in GlobalConfiguration.cpp

When I try to run it for a particular network, I get the following error:
"Caught a MarabouError. Code: 8. Message: Error! Have 288 infinite bounds"

From my understanding, the bounds on the input nodes haven't been propagated further. How can I correctly turn off the preprocesing step?
