Test suite exposed but not correctly

[BenWildeman]

Description

The internal test suite was exposed in #1039 however, this is still not usable because it relies on imports from internal. we cannot import internal.WantEvent for example as the internal package is restricted to the New Relic package itself. This is due to Go not allowing the internal package from being exposed as this is code meant to be hidden away from comsumers of the module.

Steps to Reproduce

actually create a repo outside of the new relic source code and try to import anything from the internal directory

Expected Behavior

all the structs used within the test suite should be properly exposed.
