Fixed possible "Operation aborted (Exception from HRESULT: 0x80004004 (E_ABORT))"

1. Do not use the `.Save();` on `EProject` because of possible "File Modification Detected ... has been modified outside the environment."
2. Do not use `.Save();` on `DProject` because of possible "Operation aborted (Exception from HRESULT: 0x80004004 (E_ABORT))"

For DProject it also activates "Save As" dialog in VS even inside try/catch
