analyze: test: Fix tidmin thinko in "empty range" test

Empty-range test added in b4824ad5 (analyze: fix ZeroDivisionErrors when
report is empty) intended to use 0xffffffffffffffff TID, but used just
'ffffffffffffffff' string instead. It was passing on py2 partly by luck,
but on py3 it fails because tidmin type is mismatched:
