Indicator doesn't show app update downloads

[Dave Morley]

STEPS:
1. Open settings
2. Open accounts
3. Add an Ubunut1 account
4. Close everything
5. Scroll down the apps scope
6. Click on the Ubuntu Store
7. Install an app
8. Keep your eye on the transfer indicator

EXPECTED:
I expect to see the green download icon and then an entry telling me what I downloaded

ACTUAL:
No indicator changes and no list of of transfers.

This started in image #11 for mako - there was an associated indicator-transfer landing

This is intentional behavior as per bug #1350771 ("Software updates listed as "Unknown Download", 0 bytes, with broken icon") where Design opines:

> What you should see: either
> (A) the transfers indicator should not exist, or
> (B) it should not list software updates, which already have their own UI, or
> (C) each update should be listed with the correct name (for example "Update to Shorts"), correct size, and correct icon.

Since (A) is not practical for RTM and since (C) is impossible at this time as the icon and title metainfo is not available for these downloads, I opted for (B).

More specifically, anything that doesn't conduct its downloads through the content-hub is no longer displayed by the transfer indicator. This also solves other bugs similar to #1350771 e.g. bug #1350307

Status changed to 'Confirmed' because the bug affects multiple users.
