updated com.google.firebase.iid (deprecated) to com.google.firebase.installations

[hyomba-pratik]

Android build failed because of deprecated imports on FCMPlugin.java

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.InstanceIdResult;

Now updated those imports to:

import com.google.firebase.installations.FirebaseInstallations;
import com.google.firebase.installations.InstallationTokenResult;

Hi @hyomba-pratik, does the build fail on some specific compileSdk/targetSdk?

Can you see if this can be merged @andrehtissot ? Let's keep your plugin going by merging PRs or providing feedbacks if they aren't good.
