Using a non-existing iri for RDFa import and Linked Data Wrapper throws: Unable to Connect to [website]

[shinobu]

Using the RDFa import or the Linked Data Wrapper import for a non-existing iri/url throws a red OntoWiki error box with the error messages, that the program can't connect to the website. An example would be http://aksw.net/NatanaelArndt instead of http://aksw.org/NatanaelArndt

so for reproduction open the property view for a resource that has no existing website (you can just write for example http://aksw.net/NatanaelArndt in the location bar and click an the 'view resource' button)

now you click on the Resource Menu and choose either import action on the bottom of the list

after a short loading time the error appears.
