Ensure unit tests do not touch any files under data, use debug instead of pry

[ngiger]

I invested a day or so to improve running the unit tests, as last week I stumbled several times over the fact, that the github unit tests were okay after my push, but failed after creating an pull request.
The following improvements went in

• Unittest do no longer touch any file under data, but use the data4tests directory
• Added src/util/workdir to
  • defined WORK_DIR as as data when running normally and as data4tests when Minitest are defined
  • define as some constants depending on WORK_DIR
  • define PROJECT_ROOT and RESOURCES_DIR for a few cases, where we must access file in the git checkout
• Removed various FileUtil.rm_rf(WORK_DIR) in minitests teardown
• Added various FileUtil.rm_rf(WORK_DIR) in minitests setup to ensure that plugins get a clean state
• Replace pry by debug everywhere (as the debug gem is now good enough and part of the Ruby std library)
• Replaced ARCHIVE_PATH by WORK_DIR
• Reworked 7 unit test to make them pass instead of skipping them

Tested, also the following jobs

• jobs/import_swissmedic reparse 43454 45199 48914 49537 66762 53662 53663 57141 56079 5170
• import_daily

Will this also work with job/import_bsv and jobs/import_swissmedic?

As I did not change any unit test and was careful when changing files under src, I am very confident, that all jobs still run. Import_daily and import_swissmedic were run just be 100% sure.
Started job/import_bsv, when it is finish I will run jobs/import_swissmedic too and report the result later here.

The two imports finished here.

jobs/import_swissmedic? one mail with the following error in it

Plugin: ODDB::SwissregPlugin
Error: DRb::DRbRemoteError
Message: 500 => Net::HTTPInternalServerError for https://www.swissreg.ch/srclient/faces/jsp/start.jsp -- unhandled response (Mechanize::ResponseCodeError)
Backtrace:

I think we can ignore it, as probably the swissreg server was unavailable

to make this PR work, a "bundle install" was necessary.
