AccessDenied when modifying transiently moved item with too many ACEs

If at least the following preconditions are fulfilled, saving a moved item fails with access denied:

1. there are more PermissionEntries in the PermissionEntryCache than the configured EagerCacheSize
2. an node is moved to a location where the user has write access through a group membership
3. a property is added to the transiently moved item

For example:
1. set the eagerCacheSize to '0'
2. create new group testgroup and user testuser
3. make testuser member of testgroup
4. create nodes /testroot/a and /testroot/a/b and /testroot/a/c
5. allow testgroup rep:write on /testroot/a
6. as testuser create /testroot/a/b/item (to verify that the user has write access)
7. as testuser move /testroot/a/b/item to /testroot/a/c/item
8. save() -> works
9. as testuser move /testroot/a/c/item back to /testroot/a/b/item AND add new property to the transient /testroot/a/b/item
10. save() -> access denied
