tests: Don't print full tape before executing

We now continuously print the output of vhs, which prints the tape as
it's being executed. Printing the full tape beforehand is just spamming
the output with unhelpful data.  We also save the tape as a test
artifact in the CI, so we can get it from there if we need it.
