Currently test binaries are stored under e.g. src/colmap/controllers/colmap_controllers_incremental_pipeline_test and ctest lists them as controllers/colmap_controllers_incremental_pipeline_test. The corresponding new names will be src/colmap/controllers/incremental_pipeline_test and src/colmap/controllers/incremental_pipeline_test while the CMake target name remains colmap_controllers_incremental_pipeline_test.

This makes it easier to compile and run binaries with a bit less typing, e.g., ninja src/colmap/controllers/incremental_pipeline_test && src/colmap/controllers/incremental_pipeline_test.
