Fix error with Shift-E #5975

E.g. two objects are selected - tesselation and profile and tesellation being active object. Using s-e with deselect tesselation object as it doens't have a usage but Bonsai would still try to run bim.enable_editing_extrusion_profile on it leading to the error.

Also fix possible issues for hotkey executed without active object (it seems all operators in hotkey do require active object)
