Title: Fixed issue with description tab showing twice

If you have a fieldset with name 'description', it will show twice.
This is the case for modules and plugins.

This PR fixes that issue.

#### Testing instructions
Install a plugin and module that use the 'description' fieldset and check the plugin/module settings of that extension.
To test you could use this extension:

This extension comes with an admin module and a system plugin.
