Do not require an ID when signing an extension

[kumar303]

Once mozilla/addons#2648 lands on AMO, web-ext can be adjusted not to post an ID to the signing service.

Supports mozilla/addons#61

• Update sign-addon for no-ID support
• Update web-ext for no-ID support
• Release sign-addon and bump the web-ext dependency

The new API endpoint is documented here http://addons-server.readthedocs.io/en/latest/topics/api/signing.html#uploading-without-an-id

This was bogus. I had the API endpoint wrong.

We shouldn't be generating a 500 from user data though, so there might be a fix we need there to return a 400 or something.

[kumar303]

I'm pretty sure the 500 was from dirty dev data (multiple objects returned). I don't really think it's worth chasing down TBH. It doesn't happen when I use the right endpoint :)

This will introduce a new option, web-ext sign --id ..., that needs documenting
