Title: Add unit tests for Express Map

Here's a few unit tests for `express-map`. Coverage is currently at:
```
Statements : 95.59% ( 65/68 )
Branches : 77.5% ( 31/40 )
Functions : 100% ( 13/13 )
Lines : 100% ( 63/63 )
```

I wanted to catch as many edge cases (with `express-annotations`) as possible, so the set-up phase for the tests is fairly large. Let me know if that needs to be minimized, or if the tests need to become more granular.
