Sync status weird behavior

[olayway]

Right after creating the site:

• the sync status shows site as being Outdated
• instead it should show: Pending -> Synced | Error

Note: since the site is shown as Outdated, the Sync button is enabled, and it shouldn't. The initial site sync is already in progress, so the button should be disabled at this point. (but it does make sense if the site was really out of date, so it's a matter of properly fetching/refreshing the site sync status.)

Right after clicking on Sync in an outdated site:

• for a brief moment there is Pending status shown AND the Sync button is enabled,
• instead, the Sync button should always be disabled when a Site is in pending state.
