Subject: [PATCH] Caught & handled 'resource_already_exists' errors (#185)

refs https://github.com/TryGhost/Ghost/issues/12065

This protects us against multiple instances of the members-api being
started simultaneously and race conditions where inbetween the initial
"GET" of a plan which returns empty, and the "POST" of a plan to create
it, another instance has already created it.
