Ash Berlin-Taylor 1b20f21a75 Escape EMR template fields to avoid invalid XML responses (#1467) 
I had an EMR step that contained a `&` and this caused the ListStep call to fail.

I've added the `| escape` filter to handle it in this case and a few other cases that look like they could suffer the same fate.
