Don't focus a profile by default in the User Manager

Don't focus a profile by default in the User Manager

When switching users, we used to focus the profile that initiated the
action. This causes weird skip-a-roos if you try to tab to a different
pod before the forced focus completes, so don't focus any pods by default.

BUG=410718
TEST=Start Chrome with --enable-new-menu. Click on "Switch Person". The
User Manager should come up, no pods should be focused, and if you try
to left arrow or right arrow really fast, the pods shouldn't jump focus.

Hi Scott,

This is a super minor change; I hope you don't mind I'm putting you down for
both the Views and Cocoa changes (the affected code is literally exactly the
same)

LGTM
