remove eager_load from test env

[dm1try]

as we have a separated spec for this case

partially reverts 752bf4c

ref #2214

[dm1try]

Would love an explanation of why this fixes that and a spec that shows that it does, please?

it does not fix anything it just shows that the lib does not load some files when eager_load is disabled(what's usually the case in dev environment)
it is also shows that a separated spec has a false positive result, as we eager load the whole lib code in the spec helper.

so, the pr is just the reply for your #2214 (comment) , the tests are red :)
