initial migration to usergroup-system for root user is governed by
superadminAccount and superadminForcePromote fields in config file
those will have default values expected for non-fork installs, but
existing fork installs will not have them and thus will never trigger
superadmin force-promotion from migration script
and allow migration script to not throw when root user is missing
this facilitates safely removing root user altogether via database query
if you don't use it
we used to store number directly into the string size field, and
during the conversion it seemed to always add ".0" at the final string,
probably because the driver or sqlite3 itself assumes float
please run yarn migrate after pulling this commit
if you skip converting the DB, file duplicates check will fail to
function
and in the future im planning to do size statistics in bigint, which
will also fail if not converted
