Prevent Xcode errors

[akofman]

Hello,

Just a fix that ensures String values are never null in order to prevent XCode issues as described in #79.
Also, if a key is null it won't be added anymore to the parsed object. With the actual version, if
a key is null, its value is used as a key :/

Thanks !

Any idea when this will be merged? @akofman's fix worked for me (tested with his fork)

Would be nice if this could be merged as it fixes the issues I am having with this library.

why is this PR causing tests to fail?

[akofman]

Hello @mreinstein, I can't access the Travis logs for this project so I can't check why the tests fail ... Could you have a look at that ?
Tests are ok if I run them locally so I guess it's maybe a node version issue. Also it looks like every PR have the same issue on this project.

@akofman I believe this is fixed with #84 so this PR could be closed.

[akofman]

@ZauberNerd Nice ! Thanks for that.

Why was this never merged? The problem #79 still exists

[ZauberNerd]

@cmaart @mreinstein because after the fixes in #84 have been merged it hasn't been released to npm again.

Can you please publish the fixed version to NPM?

[mreinstein]
