Make map functions distinct with each invocation

[sebastianrothbucher]

Overview

Issue 548 points out that tests fail randomly when using ad-hoc queries (i.e. create a design doc, query it, remove it again). Though I can't reproduce it (not even by doing this cycle three times in a row without wait in-between), there is a solution by simply adding comments to the map function (hence changing the signature, allowing two otherwise similar views to co-exist. As it's hardly production relevant (design docs likely won't and probably shouldn't be created and removed all the time - it's a performance no-go in most cases), we actually get better tests as they really indicate if things go wrong (instead of failing randomly and being ignored after some time).

In short: improves the quality of javascript tests

Yes, thanks. This is exactly the sort of thing I had in mind for #548
