makeLinkDataKeyUnique method
This method is called when a link data object is added to the model to make sure that #getKeyForLinkData returns a unique key value.
The key value should be unique within the set of data managed by this model: #linkDataArray. If the key is already in use, this will assign an unused number to the #linkKeyProperty property on the data.
If you want to customize the way in which link data gets a unique key, you can set the #makeUniqueKeyFunction functional property.
If the link data object is already in the model and you want to change its key value, call #setKeyForLinkData and give it a new unique key value. @param {ObjectData} linkdata a JavaScript object represented by a link @since 1.6
