Fix failing Dockerfile build

[dehidehidehi]

The Dockerfile builds properly.
However, and this is probably a seperate issue : I'm having trouble making any task sync command work properly.

See #102

The docker image entrypoint starts the taskd server.
Which was not the case previously.

Thank you for your effort towards restoring the dockerfile functionality. I will merge it as I believe it improves the current situation. For completeness, when I run:
docker build .
or
docker build -t tw-install .
I get the following errors:

and when I run:

docker run \
-p 53589:53589 \
-e TW_USERNAME=First \
-e TW_ORGANISATION=Public \
--name tw-instance \
-d \
tw-install

I get:

Unable to find image 'tw-install:latest' locally
docker: Error response from daemon: pull access denied for tw-install, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.

I appreciate you took the time to install cron inside the docker, and once again thank you for your effort, I greatly appreciate it!
