Device Info plugin should not try to access the activity during registration

[alanrussian]

In order to support background execution, plugins can't store the activity as a field during registration time because the activity may not yet be available. The device info plugin was recently changed to do this.

Two possible fixes:

• If the application context will work, store the application context instead of the activity context. IIRC you can do this with the Registrar#context method.

• If the activity context is required, store the Registrar and call Registrar#activity when its used.
