Add a TLS version consistency check during session resumption

Add a TLS version consistency check during session resumption

This is a temporary fix for while we are still using the old session
resumption logic in the TLSv1.3 code. Due to differences in EXTMS support
we can't resume a <=TLSv1.2 session in a TLSv1.3 connection (the EXTMS
consistency check causes the connection to abort). This causes test
failures.

Ultimately we will rewrite the session resumption logic for TLSv1.3 so this
problem will go away. But until then we need a quick fix to keep the tests
happy.
