Change package to avoid conflicts

[bootstraponline]

I think we should use a different name for appium's flavor of the api demos. It's conflicting with the preinstalled api demos. I can't run any tests with it on Sauce because the old one must be uninstalled first.

package="com.example.android.apis">

What do you think of changing this to:

package="io.appium.android.apis">

I guess this isn't sauce specific. The Ruby test worked correctly using api demos. It would still be nice to not worry about conflicts.

👍 for changing the package.
