Fix a memory leak in program_test.cc
Program::RemoveFixedBocks will happily drop all fixed parameter
and residual blocks. So if it is called on the one and only copy
of a program, like it was being called in the tests, this will
result in a memory leak because we would have lost track of the
fixed parameter and residual blocks.
This is not a problem in actual usage since CreateReducedProgram
will first create a copy of the program and then remove the fixed
blocks from it. But in the tests, we were creating a ProblemImpl
and then calling RemovedFixedBlocks on the underlying program
object causing a memory leak.
The fix to make a copy in the tests and then work on that. I
have also added a warning in program.h
