DevTools: [Persistence] tabs should not change order during reload

During page reload, the network UISourceCodes are removed and then
re-added. This results in bindings being removed and then re-added.

However, currently we're not doing a good job maintaining the selected
tab and the tab order - they're getting shuffled during this process.

This patch fixes the behavior so that the reload does not mess tabs
order.
