BUG: report connected to deleted semantic model cannot be opened in PBI desktop

I've said before Microsoft need to make sure that pbix files can be opened regardless of errors that are hiding in files. There is a similar issue when opening .pbit files for semantic models that for whatever reason can't be refreshed on opening. If the refresh is cancelled, instead of just creating the new .pbix from template, a blank is created instead. This is poor design and needs rectifying
