fix(Templating): Hide total progress when all files cancelled

When the total progress bar is reset is should be hidden.
Also, when the percentage for total progress is calculated the case when the
total bytes is 0 should be discarded because it a) provides a bad value for
the progress bar due to a divide by zero, and b) redraws the progress bar when a a file has been cancelled.

Fixes #1303
test(total-progress): Ensure total progress is hidden when both files are cancelled
test(Templating): Total progress bar update, hide and show
chore: Increment build number
