Can't you just use this line? You should be able to assign a const string to a
non-const variable.

In any case, don't leave commented-out code in the CL.

+  const_cast<std::string&>(last_removed_configuration_path_) = service_path;

I'm pretty sure you can do the same thing with a mock using WillOnce or
WillByDefault().
