Subject: Remove all uses of Scope::Guard from the tests, use our own version
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=bbf6a9a5d39cbf1c9d22cccd298ae95ac0fef694;p=dbsrgits%2FDBIx-Class-Historic.git

Remove all uses of Scope::Guard from the tests, use our own version

A deferred constraints rework several commits later will remove all remaining
uses from lib/ and as such we will lose the dep entirely
