st2sdk bootstrap ${pack_name} is broken.

st2sdk bootstrap ${pack_name} creates version as "0.1". This breaks pack registration.

Also, description is left to "" which also breaks pack registration.

Let's please also add test for this so we prevent such issues in the future.

We should be able to utilize "pack and resource register" check have on st2contrib / StackStorm-Exchange - https://github.com/StackStorm-Exchange/ci/blob/master/.circle/Makefile#L44.
