Queries without AC using allAvailableModels

[MichaelMartin]

This needs often to unresponsive queries if there are more than 10 / 15 FROM clauses included.

Maybe better to query the whole store then. (WITHOUT FROM clauses)

->Virtuoso is answering sometimes with errors such as: Estimated Time for query etc.pp.

Actually this is a feature request to improve the performance of Erfurt, but I don't know if this might be risky …
