I'm pretty sure they did go see Dastari in "The Black Hole" and it does line up with "The Two Doctors".

Any seeming discrepancies with "The Two Doctors" can simply be accounted to the Doctor not remembering the event that well because it involved his future self, and that tends to make the younger incarnation involved lose their memories (as per "The Day of the Doctor"). So the Second Doctor only remembers Dastari having been busy with Sontarans because of that.

Everything else (getting the Stattenheim remote control, Victoria studying graphology) lines up with "The Two Doctors".
