Switch remaining TLS resumption tests to EmbeddedTestServer

Most of the tests weren't actually using the recording features of
ssl-session-cache. The one test that did was merely testing that
resumption happened. SSLInfo suffices for that.

This lets us delete the session cache recording machinery, which is less
code to port to Python 3.
