Ensure that we can format and safetly remove 10 times wihtout issues by querying the drives after each action and updating the internal cache. Improve UI to make sure that a format cannot be done when a device is no mounted.

Ensure that we can format and safetly remove 10 times wihtout issues by querying the drives after each action and updating the internal cache. Improve UI to make sure that a format cannot be done when a device is no mounted.

To test this branch please try the following:

* Safetly remove several times. Once a device is removed formatting cannot be done via the ui.
* Remove the device when a confirmation diagram is shown. The app should not crash and the device and the dialog can be closed choosing any option.
* Format works several times.
* Format does not work if an other app uses the device and an message is shown to the user.
