ryyst bd1d1c2c7c style: minor formatting cleanup in test_conflict.go
Remove extra trailing space in comment for consistency.

This utility was originally added in commit 138b5ed to create timestamp
collision scenarios for testing the sophisticated conflict resolution
system. The conflict resolution test it enables now passes consistently
after fixing the timestamp collision handling logic.
