CSV output always returns at least two rows

[pombredanne]

One one should be returned. For instance scancode -l -f csv returns an empty row plus the licensing rows.

I'm working on this one ! @pombredanne

I've figured out the solution, notice the difference :
Initially :

./scancode -c -f csv something.txt
Scanning files for: copyrights with 1 process(es)...
Scanning files...
[####################] 1                       
Scanning done.
Scan statistics: 1 files scanned in 0s.
Scan options:    copyrights with 1 process(es).
Scanning speed:  1.58 files per sec.
Scanning time:   0s.
Indexing time:   0s.
Saving results.
Resource,scan_errors
/Trash_files/something.txt,

After the bug has been resolved :

./scancode -c -f csv /home/yash/Misc/Trash_files/something.txt
Scanning files for: copyrights with 1 process(es)...
Scanning files...
[####################] 1                       
Scanning done.
Scan statistics: 1 files scanned in 0s.
Scan options:    copyrights with 1 process(es).
Scanning speed:  1.2 files per sec.
Scanning time:   0s.
Indexing time:   0s.
Saving results.
Resource,scan_errors

Spoiler: Notice the last line in both cases.

Thanks! this likely needs some rebasing on the latest develop

I am not inclined to add this as a feature and make an exception for a special case: in the end storing tree in square tables is a hard problem. Instead I would rather have a separate feature that would flatten the CSV entirely as in #830
