I had initially thought I could skip a retain in these cases since
we can trivially track the lifetime of the reference, but I ran into
a segfault in a test that used the empty string, which I tracked
down to here.
I'm not totally sure what's actually going on under the hood, but I
do know that this fixes my crash and also that I was being overly
clever anyway.
