If an object has multiple node assignments then it is always the section ID of the object referenced by the parent of the main node that will be used. In addition, if the main node of an object with multiple node assignments is changed then the section ID of that object will be updated.

bug: secion ID is not updated

Do the following to trigger the situation:
1. locate a test object in the standard section (content structure tree), if you do not have one, create a new one. Let us refer to this object as X
2. add a secondary location to X, choose some folder in the media section
3. set the main location of X to be the one in the media section
(4. remove all secondary locations, in other words make sure that the only location for X is in the media section )

After step 3 when examining X you will see that it still has the standard section, despite that its main location is the media section. This does not change with step 4. In other words, the operation changing the main location does not work as specified in these versions. Object X is accessible via ../content/view/full/id-of-X, but according to its location it should not be.
