Test preparing kanary to development

we have to import it manually. Only this overwritten command,
can sync apps that does not have migrations

#. Check report adverts count - should be none, since they're being created
in fill_campaigns only
#. run fill_campaigns and fill_reports command
#. check number of report adverts
#. Try to read data from all models.
If someone will forget about migrations, that's where we'll hit exceptions
