Fix potential for compiler warning in GlobalVisTestFor().

Browse Source 
In d9d8aa9bb9a I added a defensive NULL assignment to protect against a
not-too-smart compiler warning about unitialized variable use after the
switch. Unfortunately I only did so on master and forgot to adjust that for
14.

Stephen noticed that there actually is a compiler warning :(.
