Fix 'Build and Debug Active File' race condition with EngineLogs (#6304)

* Fix 'Build and Debug Active File' race condition with EngineLogs

If users use 'Build and Debug Active File' with "engineLogging", the resolveDebugConfigurations will quickly switch to the output window and `${fileBasenameNoExtension}` will resolve to something similar to `./extension-output-#5`.

This may be a bug with VS Code determining the output window to be a file, but this will unblock users who need to enable engine logging for this scenario.
