Do not remove password when new line is missing

If the password file doesn't end with a new line, the last line is
ignored because `read -r` will return a non-zero status, while still
setting the `$line` variable. Some implementations of pass, like
`gopass` do not create a password file ending with a new line.
Therefore, using `pass otp append` on these files will result in the
password being remove from the file.

To fix that, we ensure we insert the new line if it is missing.

I have added a test, but this is not enough to catch the problem
because `pass` will add the new line even when it is missing (for
example, using `echo -n | pass insert -e passfile` won't help to
trigger the bug).
