This commit updates all tests to enforce the Python3 executable. This is
necessary because the `assertRegex` function we use was renamed to this
name only in Python 3.2 [1]
For reference:

- Fix a bug where 'print.empty.columns=no' resulted in never printing the
project column because ColProject::measure did not take into account
the length of the last word of the project name.
- Unit tests.
- Add the configuration variable 'print.empty.columns'.
- If this variable is set to 'no', columns with all empty values are not
printed. This variable defaults to 'yes' (thus nothing is changed
by default).
- Updated taskrc.5.in to mention the new variable.
- Added unit tests.
