Issue with setting appex extension on add target

[ajnrajeev]

Hi,
I am using version": "0.8.9". I was adding a target using addTarget(tgtNameStr, 'app_extension'), but the resultant target is set as .undefined.
It looks like the function defaultExtension is creating an issue in pbxFile.js

var filetype = fileRef.lastKnownFileType || fileRef.explicitFileType;

This is settings filetype to unknown since fileRef.lastKnownFileType gets set as such in pbxFile().
After changing the order here, to pick explicitFileType first if present, the following condition created an issue

if(FILETYPE_BY_EXTENSION[unquoted(extension)] === filetype )

because FILETYPE_BY_EXTENSION[unquoted(extension)] was evaluating to wrapper.app-extension whereas filetype was "wrapper.app-extension", with the quotes.

It is working for me after I made 2 changes

var filetype = fileRef.explicitFileType || fileRef.lastKnownFileType;

if(FILETYPE_BY_EXTENSION[unquoted(extension)] === unquoted(filetype) )

Not sure if this is the right way to handle this since the function is a common one. Please take a look.

Anjana
