test: fix assert.throws error in test-http-parser

The third argument of `assert.throws()` is a message that is used by the
AssertionError, not the message to check in the thrown error. It appears
that there is an assert.throws() in test-http-parser that expects the
latter behavior. Rewrite the call to check the error message. Even if
this wasn't a mistake, this change results in a more robust check.
