Bug #12479: Regression: Regex matching against non-existant facts results in
false-positive

Branch:
Non-existant facts are stringify-ing under the hood as something, which causes
them to match regexes, despite returning nil when otherwise asked.
A simple bash script to test:
----
#!/bin/bash
for LOLWUT in {a..z}
do
cat <<- EOF > /tmp/test.pp
case \$wtf {
/$LOLWUT/: {
notice("The fact[\$wtf] matches the regex /$LOLWUT/")
}
default: {
notice("The fact[\$wtf] does NOT match the regex
/$LOLWUT/")
}
}
notice(\$facility)
EOF
puppet apply /tmp/test.pp
done
----
Expected result:
All notices that the non-existant fact doesn't match.
Actual result:
Various and sundry notices that it matched. BAD PUPPET! NO COOKIE!
