Writing Unit-test for fossdash related files.

[darshank15]

Need to write the unit-test for code written related to fossdash.

For PHP Files

• src/lib/php/fossdash-config.php ==> fossology/src/lib/php/tests/test_fossdash-config.php

For Python Files.
* fossdash-publish.py ==> No Unit-Test file for this. Also, Figure out the unit-test framework for python.
