Tests for connecting mep elements and regenerating them

Also:
- fixed bug with bim.mep_connect_elements not considering actual blender blender object's position
- moved syncing ifc position with blender object position to tools (sync_object_ifc_position)
- fixed a bug in adding a bend that occured if either any of the start/end points of the start/end segments matched - in that case one of the segments end up not connected to the bend
