Cordova returns unknown errors messages when symlinks are pointing to bad locations

Steps to reproduce:
1. npm install cordova
2. cordova create project
3. cd project
4. cordova platform add firefoxos
5. cordova platform remove firefoxos
6. mv ~/.cordova/lib/firefoxos/cordova/3.1.0 ~/.cordova/lib/firefoxos/cordova/3.1.0-orig
7. ln -s /no/such/firefoxos ~/.cordova/lib/firefoxos/cordova/3.1.0
8. cordova platform add firefoxos

Actual result:
Error that comes back that doesn't really say what is wrong:
shell.js: internal error
Error: EEXIST, file already exists '~/.cordova/lib/firefoxos/cordova/3.1.0'

Expected result:
Some sort of error that says something like this:
[Error: Unable to fetch platform blackberry10: ~/.cordova/lib/firefoxos/cordova/3.1.0 points to non-existent or unreadable location: /no/such/firefoxos]
