No provider for Keyboard! when using the new Keyboard import during tests


#1

I made a GitHub issue on the keyboard repo, but it seems like nobody is really response on it. https://github.com/ionic-team/ionic-plugin-keyboard/issues/281

I can replicate this Issue by using the test demo repo https://github.com/lathonez/clicker by replacing the Keyboard imports from `ionic-angular’ with the new, recommended version of Keyboard.
