sms: give up on an attachment that cannot be read

The return value of QFile::open was dropped, which the compiler points out
now that the method is marked nodiscard. What stood in for it was a call to
QFile::exists, so a file that is there but cannot be read went on to be sent
as an attachment with no content in it.

Take the answer from open and say in the log why the attachment is being
dropped. An open that succeeds already tells us the file is there, so the
call to exists goes away with it.
