docker-compose install instructions should use cachetdocker_cachet_1 as container reference

[jbayer]

after docker-compose up the next two commands currently have the wrong container reference

should be:

docker exec -i cachetdocker_cachet_1  php artisan key:generate
docker exec -i cachetdocker_cachet_1  php artisan app:install

The prefix is automatically generated depending on the name of the directory you cloned into. So it may be different on every system.

sure, but the default instructions would be best done to match the clone instructions [1] in my opinion.

git clone https://github.com/cachethq/Docker.git cachet-docker

Ah right, didn't realize we had diverged there. Will get this fixed up.
