Fix bug in putting previous scheduled send time in compose toolbar
Fix bug in putting previous scheduled send time in compose toolbar

If the user adds the send time text box to the compose toolbar and
then edits a previously scheduled message, the previous send time is
supposed to show up in the text box automatically, but instead the
word "long" was showing up because I forgot a couple of curly braces
in a date formatting string. I'm amazed that this has been broken for
almost six months and no one has mentioned it to me before now.
