CsvReader does not accept files in another directory

[alaindebecker]

bonobo.CsvReader('../input.csv') gives an error.
However the file exists and bonobo.CsvReader('input.csv') works fine when the same file is moved into the working directory.

The error comes from:
fs.errors.IllegalBackReference path '../Employees.txt' contains back-references outside of filesystem
which tends to indicate that the root of the fs is reset by bonobo.

Note that the log message tells the error is generated at line 56 of bonobo\nodes\io\base.py. While in github this script has only 46 lines.

@alaindebecker Try the same solution as #398. I'm sure that'll fix both the issues.

I know it's probably the same issue. When issue #398 will be solved, I'll try if the workaround works here.
