Truncation warning error in PulsarSimulateCoherenceGW.c

The conda builds are erroring due to a string formatting error in lalpulsar:

I think this was recently addressed in !963 (merged) and !965 (merged), but conda builds (gcc-7.3.0) seem to require something more to happen, I don't understand what that should be.
