system group renamed to system0

Summary

Version 9.2.5 migrated my system group path to system0. This is really bad idea as it breaks everything related to cloned path. It is not just .git/config change but also everything relying on git paths. For example, such projects in Go won't be valid anymore and each project in system group has to be modified to became "go gettable" again. I don't know what was the reason to make "Path system is a reserved name" but this is really huge issue for anyone used "system" group prior to 9.2.5

Steps to reproduce

install anything prior to 9.2.5, add "system" group, upgrade to 9.2.5 and see it renamed to "system0"

What is the current bug behavior?

system group renamed (migrated) to system0 automatically

What is the expected correct behavior?

it should not touch any of my groups and rename it
