Add tests for Autosuggest Component

[precious-onyenaucheya-ons]

The usage of the onsAutosuggest component(where input is added as a parameter) within the navigation component was not updated as part of the last release which has resulted in a bug. This has been fixed now but we need to add tests to cover this scenario so that it is not repeated

first we need to add an example for the navigation component. Probably a header example that uses the navigation macro with that param set would be best. Then this will be added to the visual tests which would be a start.
