Lookup cached basic-auth credentials with the correct key

Browse source 
Credentials cached in 'url-basic-auth-storage' are keyed by
"server:port", but were being looked up by just "server" in
'url-basic-auth'.
* lisp/url/url-auth.el (url-basic-auth): Lookup cached basic auth
credentials by "server:port".  (Bug#79486)

* test/lisp/url/url-auth-tests.el (url-auth-test-auth-retrieve-cache):
Check the digest auth test-cases cache retrieval test cases against the
basic auth logic.
