fix(makefile): test-endtoend working as intended

[sbres]

The cd was one level too deep and was not running the tests
Also added added logging of the error on generation to help debug

I should probably add a comment to the Makefile, but this is currently working as intended. The build-endtoend and test-endtoend targets build and run the tests for the generated code in endtoend/testdata. test-endtoend is not meant to run the end to end tests. Those are run using make test.

I'm not sure what you are testing with test-endtoend then.
As there is not a single test inside the testdata directory, is it just there to be sure the files in testdata are valid go files ?

That's a very good point.

$ find internal/endtoend/testdata/ | grep _test
# nothing

I have no idea why make test failed the first time I tried that sent me on this tangent.

make test is correctly running the endtoend tests and does not need the db 👍
