message_list: added pressedTint feature
It allows to see a tint color on the message when it is pressed. Moved `MessageWithPossibleSender` to `StatefulWidget` and used `ModalStatus` return type of `showMessageActionSheet` to check whether BottomSheet is open or not. Added `pressedTint` to `DesignVariables` for using it in `MessageWithPossibleSender`. Added tests too in `message_list_test.dart`. Fixes: #1142
