Fix jniThrowException to print correct error message in NativeMultinetworkJni.cpp
The parameters `actual` and `expected` in the macros EXPECT_{GE,GT,EQ}
can be a statement. If their returned value are different, it results
in them being called twice. Some statements are not supposed to be
called more than once, such as expectAnswersValid that automatically
closes the fd.
