endpoint test

[jcromanu]

change expected input for request type :
input createUserRequest
and expected output :
expectedOutput createUserResponse

instead of

	input          getUserRequest
	expectedOutput entities.User

and delete conditionals inside the test

from
ep := makeGetUserEndpoint(serviceMock, logger)
if !ok {
t.Errorf("Error parsing user response on test")
return
}

to
result, err := ep(ctx, tc.input)
assert.Equal(t, tc.expectedError, err, "Error on service create user ")
