Fix bug where environmentVariables or systemProperties can contain no…

[shawjef3]

${project.basedir} can't be used as an environmentVariable without this patch. It gives a class cast exception.

I released this as me.jeffshaw.scalatest:scalatest-maven-plugin:2.0.0-M1.

It's been sometime, so just wanted to see if it is still relevant.

Thank you for your pull request and welcome to our community. We could not parse the GitHub identity of the following contributors: Jeff Shaw.
This is most likely caused by a git client misconfiguration; please make sure to:

1. check if your git client is configured with an email to sign commits git config --list | grep email
2. If not, set it up using git config --global user.email email@example.com
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails
