Version 4.9.0 breaks AppCompatDelegate usage

[str4d]

To properly use AppCompatDelegate it is necessary to initialize it before super.onCreate() is called:

protected void onCreate(Bundle savedInstanceState) {
    getDelegate().installViewFactory();
    getDelegate().onCreate(savedInstanceState);
    super.onCreate(savedInstanceState);

    // ...
}

With the hardening added to BaseCrashReportDialog in #413, this is no longer possible. A preInit(Bundle savedInstanceState) method in BaseCrashReportDialog would resolve this.
