[BUG] Failing travis test builds due to pipenv

[ultraheroe]

Description

Some roles generated with this cookiecutter are failing at travis.ci build because "old pipenv installation" during tests.

In fact, no installation is the problem, the referred command will do the installation under the selected dist selected in .travis.yml only if pipenv isn't installed yet. So if a old dist, probably comes with old pipenv and then fail the build due to old dependencies failing tree.

Steps to Reproduce

1. Generate a role using this cookiecutter
2. ??
3. Upload it and let travis try to test build.

Expected behavior:
No travis test build failing

Actual behavior:
Travis test build fail

Reproduces how often:
When old dist with old pipenv used in .travis.yml
