btknu 6e72169ffe Add missing script key to Travis CI config (#1950)
* Add failing test for travis.yml

I see three options to test travis.yml :

1. Testing that the YAML contains relevant value. Least useful and least
reliable, but simplest to implement.

2. Testing that the YAML is valid TravisCI YAML. Unfortunately this is
difficult / impossible. Doing 'travis lint' would succeed, this command
does not check for 'script' key presence and wouldn't be useful for us.

We could use 'travis-build' to verify that the YAML can be converted to
a worker config, but as of now 'travis-build' doesn't work out of the
box.

There is a new tool for validating travis YAML files 'travis-yml', but
as of now it's a ruby-only library and it's still a work in progress.

3. Running Travis CI task based on the generated YAML. This seems the
best approach, however since cookiecutter-django itself uses Travis CI,
that would require running Travis CI from within Travis CI.

Scheduling Travis CI job without a github push still requires a public
github repo, which is something that we can't generate on demand.

Given that I'm opting to use approach 1.

* Adds missing config to generated .travis.yml

The keys added are as follows:

1. 'script'

Required by Travis, cookiecutter-django used to provide it until it has
been removed together with hitch.

I'm assuming hitch has been replaced with pytest, I'm setting pytest as
the new value for the 'script' key.

2. 'install'

Not required by Travis, but necessary in our case; installs test
libraries, mostly pytest.

As of now this points to 'local.txt' requirements file. There used to be
a separate 'test.txt' requirements file but it has been decided to merge
it with 'local.txt', see discussion in
https://github.com/pydanny/cookiecutter-django/pull/1557 .
