Suggesting fast track here, as this fixes an issue in "main" when one enables debug events.

Correction - the original idea of just getting the pipe name broke many unit tests because there is (strangely) a debug event for getting a pipe name, and all unit test event counts became wrong again. Simpler and better fix to just not print the name, only ID.

We should also remove the debug event on CFE_SB_GetPipeName success. This generates a large number of clutter events, and makes UT fragile, and none of the other "get name" APIs have an event on success.
