Statistics wrong if using --jobs argument

Support we have two files, first.py and second.py that both have one line inside:

pass

pylint first.py second.py and pylint --jobs=2 first.py second.py produce different output.

Interesting parts from the diff:

-3 statements analysed.
+4 statements analysed.

In fact, there are just two statements.

-% errors / warnings by module

The whole section is missing.

-|missing-docstring |2           |
+|missing-docstring |1           |

There are actually two missing docstrings. Both invocations emitted two missing-docstring messages, but the stats in the report are wrong.

Improve the message report for --jobs. Closes issue #501.

Should be fixed now. The "errors / warnings" missing section and the message stats problem was fixed by 158aca284889, while the different number of statements was fixed by d69d5b71899ac0b0354e65b490183df1f72e8fd1
