Command 'Move object among projects...' relocates corpus object physically but not logically.

[JKatzwinkel]

Description

When attempting to move a corpus object from one corpus to another, the object gets removed from the source collection and appears in the target collection. However, its partOf relation to the source corpus remains the same, which effectively makes it disappear from corpus navigator?

Expected behaviour

Any partOf relation between the moved object and the source corpus should be overwritten with the target corpus as the new object of the relation.
