Don't emit info on op during reproducer error emission

[jpienaar]

Summary

This avoids dumping the module post emitting a reproducer, which results in
many MB logs where a reproducer has already been neatly generated and obscures
the error that led to the failure.

You can remove both if and replace the true with shouldPrintOnOp here.
