elelphant: get-instances-by-...

[lgiessmann]

1) no instances are returned when store-controller was reopened (even if the controller wasn't closed)

2) errors when requesting for AssociationC, RoleC, ... that are not reasonable

• these errors (1+2) are not happaning on isidorus.ztt... - seems like this is depending in the sbcl-version???

[lgiessmann]

importer_test.lisp
-> (elephant:open-store (xml-importer:get-store-spec dir)) cuases a problem -> some objects are missing

appears in the tests:
*test-setup-repository-xtm1.0
*test-variants-xtm1.0

[lgiessmann]

it seems that the last created object that should be persistet is transient and never stored in the actual DB

[lgiessmann]

--> appears if the function elephant:open-store is called with an store-constroller that s already open.

--> solution: open-store is only called after the store-controller was closed after an import
