Call source .env before exporting bash environment variables ( I guess they are default values for sail )

closes #206

This has the effect of making the APP_PORT default value in docker-compose.yml redundant. I had configured a default APP_PORT value of 8080 in my project like so:

    ports:
        - '${APP_PORT:-8080}:80'

but the default is defined in vendor/bin/sail which means APP_PORT is never undefined and will always default to 80 when there's no value in .env. Perhaps the provided docker-compose.yml should look like this to avoid confusion:

    ports:
        - '$APP_PORT:80'

@cameronmurphy
Thank you for pointing the possible confusion.
I will take a look at it.
