accept-whitelist instead of accept_whitelist in config is causing error

[Fatal-Errol]

I did a composer update and an error occured after that:

Fatal error: Uncaught exception 'Zend\Stdlib\Exception\BadMethodCallException' with message 'The option "accept-whitelist" does not have a callable "setAccept-whitelist" ("setaccept-whitelist") setter method which must be defined' in /var/www/engine/canarium-appmaster/forms/vendor/zendframework/zendframework/library/Zend/ServiceManager/ServiceManager.php on line 946
( ! ) Zend\Stdlib\Exception\BadMethodCallException: The option "accept-whitelist" does not have a callable "setAccept-whitelist" ("setaccept-whitelist") setter method which must be defined in /var/www/engine/canarium-appmaster/forms/vendor/zendframework/zendframework/library/Zend/Stdlib/AbstractOptions.php on line 110

I checked the source and it seems that the accept-whitelist is causing it in config/admin.config.php. The zf-content-negotiation is expecting an underscore as a separator so changing it to accept_whitelist solves the problem.

Maybe a recent update on dependent packages is also causing this since it was working fine before the update.

Thanks

zf-content-negotiation versions 1.0.9 and 1.1.1 now allow the dash-separated configuration keys. One thing to note: prior to the change that introduces the above exception, dash-separated keys were silently ignored. The patch in zf-content-negotiation now recognizes them. The appropriate fix is for this module to use correct keys, however.

@weierophinney they get overridden by each other though, so the problem still exists, no matter how they are seperated.

This needs a merge now.
