Fix an issue where changing a table collation could cause an exception (fixes #2320)

This issue probably was introduced in f02fb787063caabe246a0ee420394f5676c55a9c

The empty item at the top of the collation list will now no longer have a selection mark, though.

+ *
+ * Note that in theory multiple menu items could have the same representedObject
