Add the account name to all the X_per_Z transform models

All our current X_per_Z transform models (e.g. fb_clicks_per_day) have and use the campaign_name, adset_name, ad_name but they do not include or group by the account_name.

That could cause issues for users fetching data from multiple accounts.

This MR adds the account_name to all those models both in the Select and the Group By clauses (for those models that perform a Group By)

Closes #2 (closed)
