Fix warnings generated when running pytest (#1519)

1. @pytest.mark.slow is not defined
2. Unsupported escape sequence "\_" in comments (which also resulted in stray `\` characters in the PDF output)
3. Prevent test_sbp2json_unbuffered() from failing once and then passing the second time
4. A user warning is triggered whenever sbp.jit is imported, so remove it
