Luke Wilde 7fae46361b LibWeb: Fix null-deref in <table> delete_row with index = -1 and no rows ...

This wasn't quite following what the spec says for step 2:
"If index is −1, then remove the last element in the rows collection
from its parent, or do nothing if the rows collection is empty."

It was behaving like:
"If index is −1 and the rows collection is not empty, then remove the
last element in the rows collection from its parent."

Which is not the same, as it will fall into the "Otherwise" if
`index == -1` and the rows collection is empty and try and get the -2nd
element of the rows.

Found with Domato.
