In the following query, the generated VALUES block contains bound bnodes, when they probably shouldn't. For example, we're getting VALUES (_:Nd1ab3cb93cb6459fa46ff4e37aef1925, … using the following query. By converting [] rdfs:label "EN Singular" (in graph and the query) to <http://example.com/foo> rdfs:label "EN Singular", this all works as expected.

Fixed the generation of VALUES block for federated queries.
The values block was including non-variable values like BNodes which resulted
in invalid queries.
Closes#2079.
In the following query, the generated
VALUES
block contains bound bnodes, when they probably shouldn't. For example, we're gettingVALUES (_:Nd1ab3cb93cb6459fa46ff4e37aef1925, …

and the query) to<http://example.com/foo> rdfs:label "EN Singular"
