Avoid multiselect ANRs

[mchowning]

Description

With the 7.45 release we've seen a significant increase in ANRs: #1314. This PR avoids the ANRs by addressing part of the underlying issue.

Note that this PR is targeting a new 7.45.1 hotfix branch because I think this should be a hotfix since it is causing thousands of ANRs a day. For that reason, I am keeping this PR small and lean (basically the simplest changes that address the ANRs), and I will open a separate PR that builds on this for a betafix release (#1316).

This fix is basically just to make sure that we avoid iterating through the multiselect items when we select or deselect all of the multiselect items.

Testing Instructions

1. Make sure you have a bunch of episodes in your Up Next queue
2. Go to a filter with a lot of episodes
3. Enter multiselection
4. Select all
5. Tap the miniplayer and then swipe up to get your Up Next queue (don't close the filters screen)
6. Enter multiselect mode
7. Select all
8. Select None
9. Observe the app locks up for a while
