Fix bug with certificate search for TLDs of other than 3 chars
Fix bug with certificate search for TLDs of other than 3 chars

The `substr` of `-8` was based on `.dev.crt`, but since the TLD has always been configurable, this should have always been dynamic.

Running `valet links` will not show `https` or the `TLS` columns correctly if the substring matching is of the wrong length.
