Error in test file node.csv

The file "node.csv" in the directory "testing" contains an extra quotation mark, which causes any attempt to import to fail.

Line 6 reads:
1. there is a user called 'robrechtj' (with email robrechtj@example.org)",

which causes the multi-line import to halt just before the comma.

Line 6 should read:
1. there is a user called 'robrechtj' (with email robrechtj@example.org),

I've attached a patch.
