Pull request #48 breaks authentication using environment variables

[phillipsnick]

This only applies to the master branch.

Was investigating the feasibility of using the basic auth fix under #49 but ran into issues with building/running under docker.

Hello! Pretty much the same issue here, but not under docker, just basic auth:

Any recommendations ?

Hi,
I had this problem today. I worked it around just creating an empty credentials file.
So in my case I just did from my user folder:
mkdir .aws && cd .aws && touch credentials.

Then run the aws-es-kibana command again and I see everything correctly.
Open this helps at least to unblock someone.

You can also -v /tmp/dummy:/root/.aws/credentials with docker
