Fix initial board creation

We cannot rely on the automatic userId setting of the collection hooks.
If a user is created during invitation, the userId field will contain
the id of the inviting user.

This fix this, by mocking the CollectionHooks.getUserId function and
returning the userId of the new user for all new documents after
creating the user.
