Fix incorrect handling of invalid negative object ids
Fix two errors introduced in #1110 and #1112. Since
#1110, encountering the invalid indirect reference #1110
-2147483648 n R produces an integer underflow which, if
undetected, immediately trigger a logic error. Since
#1112, object -1 0 R may be incorrectly identified as
an earlier generation of itself and deleted,
invalidating a live iterator.
