test: Exercise magic-from guessing with a single configured address

Immediately after releasing 0.3 we learned that the magic-from-guessing
code could hang in an infinite loop in some cases. The bug occurred
only when the user had configured only a primary email addresss and no
other email addresses.

The test suite wasn't previously covering this case, so address this
shortcoming.
