Turn off autocomplete in JavaScript's addAuthor form

[Janell-Huyck]

In the addAuthor javascript function in app/assets/javascripts/ either in its own file or in application.js, we have a function addAuthor that includes manually creating lines inside a form. Those lines need to have autocomplete='off' on each line to prevent the form from being filled when the user uses the back-arrow. This is a security fix.

Example old code to modify:
<input type="text" name="${type}[author_last_name][]" id="${type}_author_last_name_" required="required" class="form-control form-group">

Must include test that checks for the autocomplete=off and when user uses back-arrow in browser, fields should not auto-complete with old information.

Waiting for merging of PR #309 before moving forward with this.
