Fix correct linking for token allocation

[dasanra]

What it solves

Link from allocation widget in header to open the Safe App is malformed, missing /app and reloads the whole web. Somehow in web is working but the desktop app is not able to resolve the link.

How this PR fixes it

Use react-router to navigate to the correct route

How to test it

Check that in prod the /app is missing when hovering the allocation widget in the header
Styles should be exactly the same. Link should correctly redirect to the Safe App

In the desktop app without this fix, app is not correctly redirected. If we use a normal link the current Wallet is disconnected
