ActivityScenario support & FontSizeTestRule bug fix

Merge pull request #6 from sergio-sastre/release/v1.1.1

Attempt to fix failing artifact

Fix bug on API25+ and add FontSizeActivityScenario

This pre-release:

• FontSizeTestRule: Changes the font size via adb command on devices and emulators running API 25+. However, this might make the tests run a bit more slowly on them
• Adds FontSizeActivityScenario for alternatively changing the font size via code through an ActivityScenario on any API. It basically opens an empty activity with the context configure with the proper font scale, and snapshots the target views in it. Has the drawback that it cannot be used to snapshot test our own activities.
