Fix dangling private tool InDetTRT_ElectronPidTool
As flagged in the JobOpts hackathon, there is currently an error message coming from InDetConfig:
Py:ComponentAccumulator ERROR Deleting a ComponentAccumulator with dangling private tool(s): InDetTRT_ElectronPidTool
This MR fixes it. It won't be seen in normal tests, since this code isn't run by default yet.
