adding a first simple test case
Finish annis-3.1.6
Merge remote-tracking branch 'tk/feature/distinct-annotations' into feature/distinct-annotations
Merged 'develop'.
some new test queries for advanced non-reflexitivity
only add non-reflexitivy condition if really needed
generalize the concept for both schemes
Use the node annotation namespace/name in the find sql generator to make the results distinct.

The distinct condition has been updated to be more conservative
Merged 'develop'.
append the node annotation namespace and name to the salt URI of the match
ignore node annotation in salt URI when parsing it for the subgraph query
"_=_" is now also non-reflexive in the newer definition
if a query node is not using annotations, fallback to NULL as the value for annotation namespace and name
fill up empty annotation namespace and name columns if a sub query has less nodes
rename "_id_" to "_ident_" to make clear this operator is not about the node ID
implement the more complex semantics for "_ident_"
