Backup & remove redis dump on reset-data
What does this Merge Request do and why?
Redis was keeping persistent state between the old and the new situation. This caused the seeds to think some repositories existed already and what not.
This MR moves the old redis/dump.rdb away so it won't interfere with seeding clean data.
This MR has a few commits extracted from !2651 (closed).
