The changes to secure_multiple_client_server_test, to test the session cache,
made in r27875, were not needed, because a copy of the test with those changes
already exists, under the name secure_session_resume_test.dart. So this CL
restores that file to its previous state.

File tests/standalone/io/https_bad_certificate_client.dart (right):

https://codereview.chromium.org/24598002/diff/1/tests/standalone/io/https_bad...
tests/standalone/io/https_bad_certificate_client.dart:65: expect(result ==
'true');  // The session cache keeps the last connection.
Changed to "may keep"
