1) '{{id:R0}}' now gives the correct record id, even on records which are 'new' (id is 0 at time of save) - '{{id:R0}}' can be used 'fileDestination' to build pathFilename.
2) Fixed problem with non existing uploads: in the past a sip has been saved instead of an empty string in the current record.
3) Fixed problem with a) choosing an upload file, b) deleting them immediately and c) pressing 'save'. Non existing temporary uploaded file has been tried to move to final destination.
