(maint) Ensure results hash is defined for module install

If the puppet module tool attempted to install a module from the
filesystem that does not exist, it would raise an error before a
variable was defined that the ensure clause needed to modify. Doing so
would raise a NoMethodError on nil, which masked the underlying issue.
This commit defines the variable at the beginning of the method to
ensure that the ensure clause works as expected.
(maint) Update puppet module version in test

Commit 674e7d2 updates the puppet module tool to follow semver.org and
use '0.1.0' as the first revision of the module. Acceptance tests were
relying on the default version being '0.0.1' which meant that the
version change broke those tests. This commit updates the version used
in the tests to match.
