Stickies should maintain entered data if your submission fails validation

[adambray]

If an invalid string is put in the "Show to users" field, the returned
error page reloads the default clusters checked. For example: I set a
sticky to show to both the TTO (where I was logged in as a blank test
shift) AND the Io. I put nonsense in the names box, and the error page I
got had only TTO checked and left Io unchecked. It would be nice if it
remembered the other, valid options we set.
