cd examples; make test fails

[jaekwon]

fails with the following error:

panic: fail on gno.land/r/demo/boards/z_0_a_filetest.gno: got "unable to determine if test is a _test or a _filetest: init.0", want: "unauthorized"

all the example tests should run on CI, not sure why it isn't.

[moul]

should be the case, we'll fix it.

[jaekwon]

fixes for the first two cases...

I'm on the CI thing on my side.
