Replace deeplink exp scheme handling with an environment variable #375
Description
We added some code to test deeplinks with expo's recommended method, but it's actually quite limited and doesn't allow passing query parameters with a custom host (how we handle deeplinks from push notifications), so I think we should remove that code and instead add a very simple check to overwrite the current link with an env variable if it's set.
