[2.1 UI] Failed to mount a partition and it doesn't surface error.

[Andres Rodriguez]

1. Commissioned a machine.
2. Umounted the root filesystem. 'sda-part1' from 'File systems'
3. Under 'available disks & partitions' select the 'Edit' button of 'sda-part1' to mount it.
4. Select a mount point to '/' & click save.
5. MAAS /appears/ to have finished successfully:
   5.1. sda-part1 is listed under 'File Systems'
   5.2. Error message shown: "Mount the root '/' filesystem to be able to deploy this node."
   5.3. You see the traceback below.
6. If you press F5, 'sda-part1' goes back to 'Available disks & Partitions'.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
