fixing test_rs2redcap_redcap2rs and reverting some changes to converters

[djarecka]

Fixing test after changes to #81

• I fixed the printing error in the test
• I change parse_html to avoid problem with joining words/lines without space

There are still issues with isVis, from original isVis set to False, after both transfromation, the isVis is set to True. I believe the redcap csv is fine, so the redcap2rs has problem.
You can check in the test tmpdir for example in output_nimh/nimh_minimal/activities/DSM5_crosscutting_adult/DSM5_crosscutting_adult_schema, elemnts like items/dsm5crossad_d_1

EDIT
I added some version of fix, by reverting #81 and removing nan from entire df
