DAE files orientation on import

[Jaffacakelover]

If I use the 'Export interpreted' option on a room to get a DAE file, then import it into Blender 2.81, it's rotated 90 degrees onto its side. The model has to be grouped and manually rotated -90 degrees on the X Axis to correct this.
(This may mess up the camera views, or I may have them set wrong)

I checked each step and it seems there is nothing wrong in the pipeline.
I suppose AITD frame is x=right, y=bottom (like screen frame), z=depth.

One easy way to prevent loosing that may be to change up_axis to Y_DOWN in DAE files.
