Fix serialized JSON sorting failure in test

This fixes a failure I got due to the sorting of keys in serialized JSON value.  The test failure was:

```
not ok 16 - http request param 0
#   Failed test 'http request param 0'
#   at t/daemon_claim.t line 119.
#     Structures begin differing at:
#          $got->[5] = '{"ttl":1,"user_data":{"some":"hash"},"resource":"foo"}'
#     $expected->[5] = '{"ttl":1,"resource":"foo","user_data":{"some":"hash"}}'
```
