[FIX] ormcache: fix calls to `ormcache` with unexpected context parameter

The implementation of `ormcache` does not work on methods that take a `context`
parameter.  Because of the decorator `decorator`, the arguments of the call are
passed positionally to the method `ormcache.lookup`, and positional arguments
are used in the cache key.

The fix consists in removing the `context` parameter from the faulty methods,
either directly, or by caching a private method called by the public method.
