Reviewed by Aditya Keerthi.

Try to speculatively fix some reports of drag and drop failing on iOS, due to the provided `NSURL`'s
last path component being equal to the empty string. This patch tries to address this by replacing
`nil` checks for the suggested name with length checks instead (such that we'll replace
`suggestedName` with the fallback value in the case of the empty string).
