Fix the MD5 computation in the src/core/writer.js file

Browse source 
Currently the MD5 computation doesn't actually work (at all?), since we're invoking the `calculateMD5` function without providing all of the necessary parameters and the PDF-data thus isn't taken into account.

Fixing this caused unit-tests to fail, which isn't that surprising since the current date/time is used in the MD5 computation, and we thus utilize Jasmine to work-around that.
