LibWeb: Consider empty fragments the same as whitespace in LineBox

Browse source 
When computing whether whitespace should be collapsed or not, we have to
consider empty fragments, since <br> will produce an empty fragment to
force a line break.

LineBox::is_empty_or_ends_in_whitespace() is amended to look at the
length of the last fragment, and return true if it is 0.
