verify that l10n option is valid before using

Make sure that the option is what we expect.

Probably caused by a not 100% valid info.xml, not sure which one though, found the issue in the logs of a customer.

I had this as well for the zimbra app: https://github.com/ZeXtras/zimbra-drive

The sentry log looks like the $options should not be iterated on but is the actual $option. 🤔

This is a working entry in the info.xml:

       <description>Authenticate Users by SQL</description>

This is a broken one:

    <description lang="en">
        <![CDATA[Add Nextcloud / ownCloud as Briefcase in Zimbra with the full features of both applications.]]></description>

So maybe something is wrong in the parser itself.
