open: use the original attachment extension if possible

When opening an attachment with :open command we make a temporary file
and open it then. The file is named randomly, but the extension is
derived from the attachment parameters.

This patch checks if the attachment has a file name assigned and takes
the extension from there. Otherwise it rolls back to the original
mime-based extension generation.
