fix(page-load-saga): ensure restricted route persists and does not switch to login route on load complete

[domw30]

Note :: Further refactoring required. We should move the android download functionality to the restricted component for the restricted route now that we would prevent the user from reaching the login route.

What does this do?

• set load to complete if restricted route is reached due to device being mobile.
• this removes test with regards to showing android download links.

Why are we making this change?

• prevents the route changing to login when page load is complete on a mobile device.

How do I test this?

• run tests as usual.

Key decisions and Risk Assessment:

Things to consider:

1. How will this affect security?
2. How will this affect performance?
3. Does this change any APIs?
