[feature] Support Actor URIs for webfinger queries (#2187)
* [feature] Support Actor URIs for webfinger queries

It's now possible to pass an Actor URI as the resource to query for when
doing a webfinger query. The code now extracts the username and domain
from the URI. The URI needs to be fully qualified, including having a
scheme of http or https to be recognised as such.

The acct scheme is handled as we used to, including dealing with an
erroneous leading @ on the username. We retain the ability to handle
resources without a scheme by parsing them again with the acct scheme if
the original parse failed. This can happen due to parsing ambiguities
when dealing with a string like user@domain.tld:port.

* [bugfix] Remove debugging changes

* [chore] Make TestExtractNamestring table-driven

* [chore] Unnest Trim and Split for readability
