Fixed missing FavIcons on Android #1640 (#1649)

* Set custom HttpClient for FFImageLoading to set AndroidClientHandler in order to load icons from icon server due to a problem with the SSL certificate when using the default HttpClientHandler #1640

* Using cleanup for FDroid  #1640

* Added System.Net.Http on Android.csproj for FDroid only to check if that fixes the build
