Making require('superagent-cache')(null, cache)
calls made after the initial require('superagent-cache')(null, cache)
call overwrite the cache
param passed in an earlier calls. This is useful when you have multiple test files that call require('superagent-cache')(null, cache)
but your test runner executes each of them from a single parent context such that each superagent-cache
instance is not garbage collected before the next one is required.
