acme: fix deadlock when Client.Key is nil

When methods that use POSTs are called on a acme.Client which has a
nil Key field it will cause a deadlock due to an infinite loop in
the code that looks up the account KID. This change adds a check for
the key being nil, and errors out if that is the case. Also adds a
test for this behavior.

Fixes golang/go#38790
