Fix sign up broken because of missing workspace schema (twentyhq#6013)

Allow workspace datasource factory to return null if the workspace
schema has not been created yet

Add calendar cron command on self-hosting-var.mdx (twentyhq#6009)

To enable Google Calendar integration, you need to run `yarn
command:prod cron:calendar:google-calendar-sync` in the worker
container. However, currently, the self-hosting guide does not tell you
how to do it. If you just follow the guide, only Gmail integration will
be enabled. So I added the command for calendar sync cron on
self-hosting-var.mdx.

Added a fallback default record chip generator (twentyhq#5860)

The record chip generator context was missing a edge were a new field of
type relation is created and not yet in the metadata so no chip
generator function can be precomputed.

For now I added a fallback default chip generator, to prevent any bug,
but we might want to add a new chip generator function while creating
the new field ?
