Only privileged users can load table data

[coleshaw]

Because of how censor revisions works in combination with the table temporary IDs, only a project's privileged users can upload table data. Not sure if this counts as a bug, or we'll just have to give all the data scientists the privileged flag (might be super difficult to work around).

You get this error thrown (relevant parts):

Because the censor uses the revision's IDs to check for restricted access, but a table revision only has temporary IDs, the query breaks and dies. The workaround is to make sure the user is a privileged user that can see and edit restricted records.
