Makes TabStrip not show focus border

This is a temporary solution. I need to make set_focusable install the
focus border (instead of constructor), but that's going to take a bit
more time and I want to land this before I go on vacation.

[Activity Log] Grant a new extension ID use of the activityLogPrivate API

Rotate extension IDs that are granted access to the activityLogPrivate
API.  Generate a new key for production use, make the old release key
the new testing key, and make the old testing key an obsolete key.
There was previously an obsolete, now-unused key, so simply drop that.
