Greyson Parrelli 59f362495a Add additional checks around link preview domains.
We never make requests to non-whitelisted domains, but there were
situations where some links would redirect to non-whitelisted domains,
which would hit a final failsafe that resulted in a crash.

To prevent this, we detect bad redirects earlier and fail more
gracefully.

Fixes #8796
