*: load password infos from users file in no-db mode not connectors

In --no-db mode, load passwords from the users file instead of the
connectors file. This allows us to remove the password infos field
from the local connector and stop loading them during connector
registration, a case that was causing panics when using a real
database (see #286).

Fixes #286
Closes #340
