It's questionable that a default license makes any sense from a legal perspective.
If the tool created the license without the user choosing it, then it may not even be applicable.
Best to let the user choose their license with intent.

* fix: ensure that testproject is removed even after a failure
* fix: defer licenseFile
* style: simply defer os.RemoveAll
* cobra/cmd: add getProject test func
These tests were time-dependent and would start failing in 2018
when the golden files still have the copyright year of 2017.
Fix by hard-coding the year 2017 for the purpose of these two tests
to ensure reproducible builds.
Fixes#503
