Enforcing controls show only on spreadsheet selection

- Modified HTML template to show/hide spreadsheet controls based on if there is a value for scope spreadsheet.url which would only be if a successful public spreadsheet was chosen
- Minor modifications to HTML template tweak some field widths and inclusion of refresh field within the containing spreadsheet controls div
- Updated e2e test file to test latest change of entire spreadsheet-controls being hidden by default
- Turning off two e2e tests as now a mock test will need to be written which will have to mock select a spreadsheet
