Install packages one at a time

Install packages one at a time

The csit_failed_tests.txt file is not being created any
more. This fixes it.

Not sure why this breaks when installing one in a single
line, but the bs4 and requests libraries aren't found
when they are installed together with tox on the same
command line.

Also, turns out that we need bs4 now instead of
beautifulsoup4.
