New Launch Instance dialog is mostly untranslatable

[Doug Fish]

After running
./run_tests.sh --makemessages
./run_tests.sh --pseudo de
./run_tests.sh --compilemessages

then running a dev server, and logging in and using German as the language, the new Launch Instance wizard is mostly untranslatable. On inspection I don't see messages like "Instance Details" or "Please provide the" in
horizon/locale/en/LC_MESSAGES/djangojs.po.

I notice that Cancel/Next/Back are pseudo-translated, but almost nothing else.

    Fixed dashboard angular translation issue

    We now have javascript files in openstack_dashboard as well. However,
    the run_test script does not account for this and only run translation on
    the horizon folder. This patch address this problem. Also removed the
    invalid gettext('') since that causes the msgid to be blank.

    Steps to test:
    1. ./run_tests.sh --makemessages
    2. ./run_tests.sh --pseudo de
    3. ./run_tests.sh --compilemessages
    4. set LAUNCH_INSTANCE_NG_ENABLED = True in local_settings.py
    5. localhost:8001/settings/ and change to deutsch
    6. localhost:port/project/instances/ and click on launch instance
