Description

FCM supports two types of messages, data and notification. The previous
fix for iOS was necessary, because apparently data messages are
difficult to handle there. However, that broke data messages for
Android. Rename the setter so we can differentiate between data and
notification messages when constructing the FCM payload.

Testing Done

Unit tests
