Add cordova-plugin-test-framework as dependency of plugin tests?

[janpio]

README says:

Q: Should I add cordova-plugin-test-framework as a of my plugin?
A: No. The end-user should decide if they want to install the test framework, not your plugin (most users won't).

But you could probably add this as a dependency for the tests themselves, so when a user installs the tests "plugin", this comes with it and the tests can automatically be run (instead of requiring a manual install of cordova-plugin-test-framework)
