Work around loadFixture error in CI

- Update all code to use the loadFixture vs their own Y.io calls.
Removed the user facing components for the browse/build buttons. Unfortunately I cannot remove the rest of the component because this component is used to control the minimized/sidebar states so it needs to stay until the browser is refactored to handle the minimized outside of this.
