Fix sessions using newTempBase or collections

Fixes after !1451 

With the RAM implementation it was possible to use in session:
 - list or dict of temp documents
 - temp documents created with `newTempBase` ( not just `newContent(temp_object=True, ...)` )

This repairs these two use cases.

See merge request !1533
