It is common to just read a few objects. Checking extraction of the
first page exercises this to make sure we don't accidentally introduce
a change that makes that case worse, such as adding an unnecessary
traversal of the file, prematurely resolving objects we don't need,
etc.

A new private overload of QPDF::makeIndirectObject breaks pikepdf's
build, so renaming function.
