Removing the build directory of a CMake project removes project name within Projects tree

Steps to reproduce:

• Load or create a CMake project (e.g. CMakeLists.txt from speedcrunch)
• set the project up by running CMake by creator's wizard
• switch to cmdline or file manager and remove the entire build directory
• switch back to creator

Expected result:

• nothing should happen - or a warning of a missing build directory should appear

Current result:

• Projects tree removes the name of the project (see attached screenshot)
