Significantly improves the usability and the result of the populate for
base models and channel/member/message.
- make populate of base models re-entrant
- adapt size to values that make sense:
- small shows something relevant, and can be quickly ran several times
- medium is fast enough to be usuable but big enough to highlight
performance issues
- large is... still not to be attempted
- avoid conflicting conditions that either make no sense or can lead to
crashes when populating the data or running the database
- better spread of data in channel/member/messages
