===========================
Attempt to fix bundles position for case scene camera has got
other constraints than CameraSolver (mostly to support camera
parenting to other object for scene orientation).
Use a bit silly logic to calculate camera matrix to orient
bundles in 3d space: temporary disable all CameraSolver
constraints for camera, re-calculate object matrix, use it
to orient bundles and clear temporary flag.
This allows to parent both of camera and mesh created from
bundles to the same Empty object and both of bundles and
mesh vertices would have the same coords in camera space.
Also removed copying of location/rotation from camera to
bundles object in "Bundles to Mesh" operator.
