Lipu Fei 12a406529e Fix inconsistent curaproject mimetype definition
CURA-5334

 - In project file writer, it says the mime type is "application/x-curaproject+xml",
   and we decided to use this as THE mime type.
 - Pass preferred_mimetype to save project file dialog so it
   automatically adds the file extension upon open.
