fix T34062 Collada exporter: changed order of export for decomposed transformation.

1.) The Blender order of applying transforms is:

Scale
Rotation
Transformation

Reasoning: This order ensures there is no shearing, which happens
when you do scaling after rotation, see also:

The Collada exporter now exports in the order how the transforms
need to be applied upon import.

2.) Also removed obsolete #if 0 lines
