Quick change. This is more concise because `uploadRows` already had a `insert` property to mark the array of values inserted into the `uploads` table, but since `uploadRows` was also used to create the `UploadMultimediaResult[]` return value of `createUploads` the the rest of the object had to be remapped in the return statement of `createUploads`.
This diff adds the `uploadResult` property to `uploadRows` when the `uploadInfos` are first mapped (by copying the same code that was mapping `uploadRows` in the return statement) so that the return statement is less redundant and can just map each element of `uploadRows` to `uploadResult`.
