Comment-out the asserts in the MailX1 and SecRecordTest tests.

The assert message `TestRuntime.AssertNotWatchOS ("X509Certificate (byte[]) doesn't work on watchOS")`
is clearly wrong as `X509Certificate (byte[])` is supposed to work on all platforms.

Still investigating whether the rest of the test will work on watchOS or not (and why if it doesn't).
