Change "Handlebars" to "handlebars" in task file to fix bug that causes Handlebars object to be undefined

This is necessary because passing in a capital "H" in the compiled files will cause an error such that the Handlebars object in the body of the code is undefined.

The following is the error I was getting in the console.
