don't hardcode firebase dependencies versions

[v1kku]

If the play-services-base dependency version requirement is "soft", then so should the firebase dependencies as they all need to be on the same version so as not to get the Multiple dex files error.

I set version at app gradle

configurations.all {
    resolutionStrategy {
        force 'com.google.android.gms:play-services-base:10.0.1'
        force 'com.google.android.gms:play-services-wallet:10.0.1'
    }
}
