IndexOutOfBoundsException while trying to insert nested paragraphs and links

[kokorins]

val bareFragment = "<p></p><a></a>"
Document("").parser().parseFragmentInput(bareFragment, Element("p"), "")

ends up with

java.lang.IndexOutOfBoundsException: Index -1 out of bounds for length 1

Reproducible using 1.14.1, but using 1.13.1 I get NPE because parser() returns null.

String bareFragment = "<p></p><a></a>";
new Document("").parser().parseFragmentInput(bareFragment, new Element("p"), "");

Thanks, fixed! Let me know if you find other issues around these parse fragments; there are clearly some edge-case bugs here because there's nothing else on the stack when created this way.
