The JS tests for the ListEditView had a couple bugs. First was that we had a mix of string characters, with both backtick strings and single-quote strings that were concatenated. This meant that the generated `<input>` element had some garbage characters in it with extra quotes and + signs. Second was that the default row HTML we were creating was only being passed to the template, and not also to the view. Testing Done: Ran js-tests and saw all djblets tests pass.
