init-database.js incompatible with restoring a database backup

[DavidBruant]

Getting errors like ERROR: relation "networks" already exists.

The database must have no tables initially for the restore to work.

It doesn't... definitions in server/database/management/createTables.sql are not copied as is in the file dump, meaning you don't have the exceptions IF NOT EXISTS, which cause the errors.
Maybe there is a solution somewhere, will need to take a look at it, but this is minor.
