Package search response has incorrect total count

[chefsalim]

Repro - issue a package search command, such as :
http GET http://localhost:9636/v1/depot/pkgs/search/testapp Authorization:Bearer:${HAB_AUTH_TOKEN}

Get back a bunch of results... and :
"range_end": 61,
"range_start": 0,
"total_count": 12

The total count should be 62

The channels API is doing some wierd things with the range as well - eg
http GET http://localhost:9636/v1/depot/channels/chefsalim/stable/pkgs Authorization:Bearer:${HAB_AUTH_TOKEN}

returns (on my machine):
{
"data": [],
"range_end": 49,
"range_start": 0,
"total_count": 0
}
