Metadata category shows in editor settings

[KoBeWi]

Tested versions

4.3 beta1 and likely earlier (though I don't remember it appearing before)

System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 31.0.15.4633) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

Issue description

In edtior settings dialog, there is a category called Metadata, at the very end of the list. Some code does set_meta()/get_meta() on EditorSettings, which is supposed to add a global pseudo-setting without showing it in the dialog. It shows in the dialog.

Steps to reproduce

1. Open dialog to create new script
2. Enable template and select some option
3. Open Editor -> Editor Settings
4. At the bottom you should see Metadata category that has e.g. script_setup_templates_dictionary
