fix no delimiter being used sometimes

The command `xkcdpass --random-delimiters --valid-delimiters=...` sometimes
would output words using the empty string as as delimiter. This commit makes
it so that when --valid-delimiters is passed, only the delimiters specified
are used, without adding an empty string in addition to those.

Closes #165.
