After a Property Entity got deleted, an Item's Claims/Statements might run into some issues. If a Claim has a Main Snak using the deleted property, the whole Claim is not shown anymore.
The Claim should still be shown but display a message that the property is deleted. The UI should allow to change the Claim's property or to delete the Claim.
The same goes for References. Each Snak of the Reference affected will not be shown anymore and in case all Snaks of a Reference are affected, the whole Reference won't be shown. Instead of not showing those Snaks, a message should be displayed and it should be possible to change the property.
Also, for Qualifiers we will run into the same problem.
