Steps to Reproduce:
Search an image regardless of value. You will get a result like this. (example: https://www.wikidata.org/wiki/Q143116).
Look at the element properties and do a new search with image and the property. Example `point in time (P585)`.

Actual Results:
No results are shown.
The generated SparqlQuery is incorrect.
```
SELECT ?item ?itemLabel WHERE {
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE]". }
?item (p:P18/ps:P18) _:anyValue.
?item (p:P585/ps:P585) _:anyValue.
}
```
Expected Results:
We should get at least [the result we found in the first search](https://www.wikidata.org/wiki/Q143116).
```
SELECT ?item ?itemLabel WHERE {
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE]". }
?item (p:P18/ps:P18) _:anyValue123 .
?item (p:P585/ps:P585) _:anyValue234 .
}
```
The `anyValue` term should be different in every triple.
