Commit 1:
Avoid printing notify object in lang selector on error
When ES is unavailable and we can't get the list of enabled scripting
langs we display a notification to the user. We were also accidentally
returning that notification object from the service method and
displaying its toString representation in the language select drop down.
Now we simplay return an empty array so the dropdown is rendered without
options.
Fixes #8636
