It was causing regressions for some half-broken files

Rationale:

Even if xref::constructXRef is returning false, that only means "i
din't find a new xref root", but constructXRef is also quite stubborn in
which it basically parses the whole file and stores the positions of all
the objects it finds, so for some half broken pdf files this is good
enough and we will be able to render those files just fine
