3D viewer: fix some issues when opened from a frame and changes are made in a other frame:

* Refresh the view only when changes are made in the caller frame.
* Allows recreate a new instances when try to open the 3D view from a frame taht is not the initial caller
* Remove duplicate code in kicad frames.
