Description

OrcaSlicer currently shows an error alert and will not export all sliced plates when an empty plate is being viewed. Exporting all plates when a non empty plate is selected has no error. The default export filename also changed depending on which plate was currently viewed because it does not make sense to include the plate object name + material + print time for a single viewed plate in the filename of a multi sliced plate gcode 3MF file.

A plate may be considered empty when all the objects in it are disabled for slicing. Disabling entire plates for slicing is useful if slicing doesn't work for some models or splitting exported multi plate sliced files into multiple files for .gcode.3mf filesize reduction.

This PR makes the export all sliced plates behavior consistent no matter which plate is currently being viewed by suggesting the project name as the export filename when exporting all sliced plates. Users can also use the "export all plate sliced" feature when viewing empty plates.

The old error:
