regression: update 0555-iPhone-REPORT for the open-ended time-range fix

Test 0555 issues an open-ended calendar-query
(<time-range start="20090827T120000Z"/>, no end). Its expected result
had baked in the previous buggy behaviour: two events dated 2011-10
(0544-gzip-PUT.ics and 0545-deflate-PUT.ics) were absent because they
fall beyond the former expand_range_end cap of start + 730 days
(2011-08-27), even though an absent end means +infinity (RFC 4791 §9.9)
and both events match the range.

With the fix they are correctly returned, so the fixture now includes
both responses. This test thus doubles as the regression test for the
fix.
