sourceMapContents array is full of nulls

[aniranc]

Reproducible example here: https://github.com/aniranc/systemjs-builder-sourceMapContents-min-failing

Looks like going through the source path normalizing (https://github.com/systemjs/builder/blob/master/lib/sourcemaps.js#L83) adds an extra ../ to the front, which causes both the attempted file read and the contentsBySource lookup to fail. Here's an example debugging session:

Any reason the paths need to be normalized here? As far as I can see the solution is just to remove the normalization, but I'm not sure of what other implications that might have.

Thanks so much for the explanation and test case. I've fixed this in fdfa6a4.

@guybedford just ran into this issue. My src/app bundle files get their contentSource correctly in the .js.map file but my jspm_packages/ bundle files have null for all the content.

I tried patching your fix into my builder code and it worked perfectly.

Thanks!
