Redirects are stripping off query parameters Anchor provides

[aaroncox]

When you click "Open Web Wallet" in Anchor, it opens the browser with a URL like this:

https://unicove.com/?auth=ihasnocpunet@active&chain=aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906

Unicove is stripping off those query parameters as it redirects the page, and they are lost. Those query parameters should be preserved.

We should also make it so that when those query parameters are provided, it acts like v1 Unicove and triggers an automatic login prompt for that account.
