Inconsistent cell state when whitelisting permanently a preset blackisted cell

[gorhill]

In the popup menu:

• Go to a site which are known to contains preset blacklisted domain names
• Whitelist one such domain
• Click padlock to make this cell permanently whitelisted
• Click the "Undo all temprary changes" icon

Result:
The permanent whitelist status of the cell (which is part of a preset blacklist) is not respected.

Fix is to reverse the order the lists are restored.
