Fixed setaccount accepting foreign address

Fixed issue https://github.com/bitcoin/bitcoin/issues/4209 where using setaccount with a foreign address causes the address to be added to your receiving addresses.
I indented just like the bit of code above mine did. You want me to fix the whole file? Or just my line?

If I fix the whole line, when I squash it I could have one commit for indentation, and one for the fix.
