[Authentication] In authenticated multi-feed setup, PM-UI: Updates window hangs if one of the feeds is not authenticated

[anangaur]

Repro steps:

1. Have multiple feeds setup with atleast one authenticated feed
2. Open PMUI, install a package that is present in atleast 2 feeds including the authenticated feed.
3. Go to updates tab

Expected: It shows the update from the feed that is accessible.

Actual: It hangs, may be trying to connect to the authenticated feed. Even so many a times the login window is not shown so user is unaware of what's going on.

The update button on the package is also not shown - may be due to the same reason.
