mod_storage_sql: Fix bypass of load procedure under prosodyctl There's no 'prosody.prosodyctl' property other than this one, introduced in 6216743c188c in 2015. Guessing that the intent was to skip this when running as a prosodyctl command. The module.command code does its own version of this initialization, so this seems likely. Thanks raja for noticing
