This improves the completion output by removing the nested special
handling. It never fully worked as expected and required a lot of
hacks to even keep it working halfway reliable. Our tests did not
cover syntax errors though and those can not be handled by this
implementation. Those break the layout and confuse the REPL.
Besides that the completion now also works in case the current line
has leading whitespace.
Also improve the error output in case the completion fails.

For tab completion, a REPLServer instance will sometimes create another
REPLServer instance. If a callback is sent to the `.complete()` function
and that callback throws an error, it will be swallowed by the nested
REPLs domain. Re-throw the error so that processes don't silently exit
without any indication of an error (including a status code).
