Nautilus will show two paritions as mounted for a USB even after that USB had a new image written to it.

When the startup disk creator writes a new image to the disk, it still displays the partitions of the USB prior to the image being written, which is problematic because after the image is written, nautilus changes all of the partitions on the sidebar to the first partition on the USB, and attempting to click on any mounted drive other than the first one listed causes nautilus to give a disk error saying there may be a bad superblock as the drive could not be opened.

Steps to Reproduce:
1. Insert a USB Drive with multiple partitions
2. Mount two of those partitions
3. Write an image to the USB drive via Startup Disk Creator
4. Notice how Nautilus shows the drives as accessible
5. Wait until the image writing is complete
6. Go back to Nautilus
7. Notice how there are two entries for the USB with the new image on it
8. Click on the second entry

Expected Results:
1. Nautilus should not show USB drives that are having its entire contents formatted and repartitioned
2. Even if 1. was intended behavior, nautilus should only have the first partition of the usb with the new image written open
3. There should be no superblock error, as nautilus should not have gotten to the point in which it reports the error in the first place.

Actual Results:
Nautilus says it is unable to access the 2nd partition even though it is not even mounted because it displayed the partitions of the usb prior to the ubuntu image being written to the USB and did not update its UI to show the USB has a new name and only has one partition mounted (the first one with the OS info on it).
