bundle: Fix "verify" output if history is complete

A more informative message for "complete" bundles was added in commit
8c3710f (tweak "bundle verify" of a complete history, 2012-06-04).

However, the prerequisites ref list is currently read *after* we
check if it equals zero, which means we never actually use the
number of prerequisite refs to decide when to print the newly
introduced message.  The code incorrectly uses the number of
references recorded in the bundle instead.
