Both caught in tests:
Fixed loss of permissions for admin users when entity restrictions were
active, since there are no entity-restrictions for the admin role but
we'd force generate them in joint permissions, which would be queried.
Fixed new role permission checks when permissions given with only the
action (eg. 'view'), since the type prefix would be required for role
permission checks. Was previously not needed as only the simpler form
was used in the jointpermissions after merge & calculation.
Tools seems to fit better since the classes were a bit of a mixed bunch
and did not always manage.
Also simplified the structure of the SlugGenerator class.
Also focused EntityContext on shelves and simplified to use session
helper.
