Files failing to scan properly in license scan tests

[ellahathaway]

The license scan tests are failing for various branches and repos with the following error:

Scan files for: licenses with 4 process(es)...
[####################] 32                                     
Scanning done.
Some files failed to scan properly:
Path: <somepath>

I believe moving to the newest scancode version should fix the issue.

v32.4.1

scancode --version && scancode --license --processes 4 --timeout 1800 --strip-root --only-findings --ignore *.ildump --json-pp /home/ellahathaway/repos/scancode-results.json /home/ellahathaway/repos/dotnet/src/roslyn/docs/wiki/documents/
