Share with yaxim: intent not cleared

[ge0rg]

When you share an image with yaxim, then switch to another app, then come back, the intent will remain in the activity stack and the image will be reposted each time you bring the original chat to the foreground.

Maybe related to this: after sharing an image, under certain conditions, yaxim thinks that the chat window is still bound and will prevent posting notifications for that window.

Steps to reproduce:

1. Open yaxim
2. Open any chat
3. Press "home" / switch apps
4. Open a file / image and "Share with..." yaxim
5. Choose (another) contact

Now, there are two ChatWindows in the activity stack, one above and one below MainWindow :(
