CMakeProjectManager: Make backup of CMake configuration before starting CMake

CMake's fileapi functionality will save the project structure in json
files in the .cmake/api/v1/reply directory.

When issuing a cmake command with -D variables CMake will update its
CMakeCache.txt file even if cmake will fail.

This commit will rename .cmake/api/v1/reply as .cmake/api/v1/reply.prev
and make a copy of CMakeCache.txt before starting CMake, and if
something fails, replace the existing files with the previous values.

Also make sure the changed values are not dissappearing when the
old .cmake/api/v1/reply gets parsed.
