When using catch_discover_tests() with DISCOVERY_MODE PRE_TEST and a
multi-config generator (e.g. Ninja Multi-Config), if a test target has
zero discoverable tests (e.g. all tests tagged with [.]), ctest fails:
CMake Error: include could not find requested file:
.../test-hidden-b12d07c_tests-Release.cmake
The early return added in catchorg#2962 (76f70b1) correctly prevented a JSON
parsing crash for zero tests, but skipped writing the ctest file. The
PRE_TEST include script unconditionally includes this file, so the
missing file causes a hard error that aborts all test discovery.
Write an empty file before returning early so the include always
succeeds.
