Wp-calypso: Activity: no rewind buttons after adding back credentials

[keoshi]

While testing the Activity log, I removed and added back credentials.

This seems to tell the UI that this site is just now being set up and originates a couple of problems:

• No rewind buttons visible across the UI; they were there before.
• “Backup underway” banner has incorrect copy: in this case we are _not_ backing up the site for the first time, and so this is not the initial backup. We should check and have different banners for different scenarios.

This is because after re-entering creds, the Rewind state is provisioning. At this point, Rewind actions like restores and backups aren't available.

A quick fix for the notice is to update the copy so instead of "We're currently backing up your site for the first time" it says something simple like "We're creating a backup of your site".

However this should be addressed in the Rewind state machine and I wrote a post about it in p9rlnk-ei-activitylogrewind
