E.193. Sortie 7.3.6

Revert erroneous changes in rule permissions checking

A patch applied in 7.3.3 to fix a corner case in rule permissions checks turns out to have disabled rule-related permissions checks in many not-so-corner cases. This would for exemple allow users to insert into views they weren't supposed to have permission to insert into. We have therefore reverted the 7.3.3 patch. The original bug will be fixed in 8.0.
