Pull request: test: add missing newlines to repl .exit writes

I noticed that some repl tests write `".exit"` in the repl, without a newline character (`\n`), as far as I can tell such write operations don't have any effect (removing those lines don't cause any test failures (AFAICT)).

I'm adding the missing newline characters so that the exit command is actually executed.

As part of this I'm also removing some `end` calls applied to the repl streams that are no longer necessary.
