Dataforms/adhoc commands: cannot pick list-single item on after first step
Gajim 1.9.2
What we did in !1051 (merged) only works when the "form with a unique field that is a list-single" is the first "step" of the adhoc. If the following step is a form of the same kind, then "next" stays greyed out and double-clicking an item has no effet.
