MXImageView: use the new interface [setImageURI:...] instead of the deprecated one [setImageURL:...] .

Note - DirectoryServerTableViewCell:
Presently the thirdPartyProtocolInstance.icon is not a Matrix Content URI. We could not use here MXKImageView setImageURI method
 without breaking the instance icon rendering. We use the deprecated interface until this point is fixed on the server side.
