[yocto] [PATCH] [yocto-ab-helper] utils.py: Resolved unicode data expansion

[Aaron Chan]

Updated patch to trigger handlestr() when unicode string is found
during iteration json.loads(config.json). Unicode and list with data
expansion were not handled hence adding this patch to handle conversion.
Added a debug message to dump pretty json data populated to ourconfig[c].

e.g "REPO_STASH_DIR" read as ${BASE_HOMEDIR}/git/mirror, where it should be
    "REPO_STASH_DIR" as /home/pokybuild/git/mirror
