Incorrect field name used to generate device name when BUILD field not included

[andymstone]

If the BUILD field is not included in the crash report then acra-storage builds the device name from BRAND, PRODUCT and PHONE_MODEL.

The problem is that on line 42 of vendor/acra-storage/utils.js it refers to doc.MODEL when it should be doc.PHONE_MODEL (as in the if statement on the line before).
