Repository: serverless/serverless (JavaScript) — Bug Fix

Issue:
`sls package` is demanding a default profile since the latest version?
# This is a Bug Report

Since the last update `sls package` requires a default profile to be set in the aws config ( or `--aws-profile` to be given ).

Not sure why the decision was made to require the aws profile even during packaging, or if this is a bug. 

It is quite anoying to us as we have a number of linting and sanity checks on the generated cf templates for which we would then have to add some aws credentials in our CI/CD for.

## Description

- What went wrong?
Running `sls package` without the default provider set or adding `--aws-profile` breaks. 

- What did you expect should have happened?
It should package the app without the need for the default profile to be set like it did before.

- What was the config you used?
The default one 

```
service: test

provider:
  name: aws
  runtime: nodejs10.x
functions:
  hello:
    handler: handler.hello
```

- What stacktrace or error message from your provider did you see?

```

Discussion:
I have similar issue, local invocation was working fine in 1.48.2 but breaks in 1.48.3 because of profile:
We install serverless globally
```
$ yarn global add serverless
yarn global v1.17.3
[1/4] Resolving packages...
warning serverless > json-refs > path-loader > superagent@3.8.3: Please note that v5.0.1+ of superagent removes User-Agent header by default, therefore you may need to add it yourself (e.g. GitHub blocks requests without a User-Agent header).  This notice will go away with v5.0.2+ once it is released.

And then call

The same for me. Works only on `1.48.2`.
@pmuens Could you please change label from `question` to `bug`? Looks like it's a breaking change or bug to be honest
