apply plugin: 'com.google.gms.google-services'

This is because you've mixed version of dependencies. The problem is because OneSignal automatically adds the following dependencies:

com.google.android.gms - Version 11.2.+
com.android.support - Version 26.1.+

So, you need to change your support, Firebase, and google play service dependencies version. It will be like this:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support:design:26.1.0'

    // Don't use +, use exact dependency version.
    //compile 'com.onesignal:OneSignal:3.+@aar'
    compile 'com.onesignal:OneSignal:[3.6.5, 3.99.99]'

    compile 'com.google.android.gms:play-services-gcm:11.2.1'
    compile "com.google.android.gms:play-services-location:11.2.1"
    compile 'com.google.firebase:firebase-messaging:11.2.1'
    compile 'com.google.firebase:firebase-ads:11.2.1'
    compile 'com.google.firebase:firebase-crash:11.2.1'

    compile 'com.github.quentin7b:android-location-tracker:3.2'
    compile 'org.jetbrains:annotations-java5:15.0'
    compile 'com.github.hotchemi:android-rate:1.0.1'
}
