Can't safely remove SD card when a background app has it open

[Bill Filler]

krillin rtm build 211

- insert SD card
- start gallery app which reads from SD card
- move gallery app to background and launch External Drives app
- click on Safely Remove button

Expected results:
- the SD card should be unmounted and safely removed. If it can't be safely removed that should be reported to the user.

Actual results:
- the app reports its' safely removed but actually it is not

Here is the error in application-legacy-ciborium-.log:

[Manuel de la Peña (mandel)]

We are working on displaying an error letting the user know that the device is in use. I don't think we can force the other processes to stop.
