odd SSL error when passing large payloads

try calling `ow.packges.get({name:"foo", junk: "SOME VERY LARGE PAYLOAD"})`

if the payload is too big (in my case, 330k), you will get back an odd SSL error:

```
Error encountered calling OpenWhisk: Error: error:0906D06C:PEM routines:PEM_read_bio:no start line"
