Resolves: tdf#136364 treat svSep type with ocUnion as range type

So for RPN
sv...Ref(ocPush), sv...Ref(ocPush), svSep(ocUnion), sv...Ref(ocPush)
another svSep(ocUnion) instead of svSep(ocSep) is appended.

Regression from

Resolves: tdf#90698 catch list (1;2) of non-references as error

that introduced a conditional check on operands and operators.
