Subject: [PATCH 2/2] test: Fix Cover block HEX test assertions

Synchronous queries of user-facing text is generally preferred over test
IDs or asynchronous queries. Additionally, the
`react-native-hsv-color-picker` must be mocked to trigger the required
interaction events. Lastly, selecting the white color results in a
non-custom color, which does not appear to display the HEX value in the
picker footer label.
