Issue:
[Bug]: TinymceBundle defaultEditorConfig is ignored
### Expected behavior

Creation of pimcore.document.editables.wysiwyg.defaultEditorConfig as described at the readme, should change the ui of the editor.

### Actual behavior

The pimcore.document.editables.wysiwyg.defaultEditorConfig is ignored.
Change public/bundles/pimcoretinymce/js/editor.js Line 74-76:
From:
`if('' !== subSpace && parent.pimcore[e.detail.context][subSpace]) {
            defaultConfig = parent.pimcore[e.detail.context][subSpace].wysiwyg ? parent.pimcore[e.detail.context][subSpace].wysiwyg.defaultEditorConfig : {};
        }`
To:
`if('' !== subSpace && pimcore[e.detail.context][subSpace]) {
            defaultConfig = pimcore[e.detail.context][subSpace].wysiwyg ? pimcore[e.detail.context][subSpace].wysiwyg.defaultEditorConfig : {};
        }`


### Steps to reproduce

Add pimcore.document.editables.wysiwyg.defaultEditorConfig as described at the readme. 
Example Config:
`pimcore.document.editables.wysiwyg.defaultEditorConfig = pimcore.document.editables.wysiwyg.defaultEditorConfig || {};
pimcore.document.editables.wysiwyg.defaultEditorConfig.toolbar1 = "undo redo | searchreplace | bold italic underline superscript subscript | removeformat | numlist bullist | alignleft aligncenter | link anchor";
pimcore.document.editables.wysiwyg.defaultEditorConfig.toolbar2 = "styles";`


Discussion / hints:
I think we can't just re-use the old way, since we need to support multiple editors in future which of course have different ways how to configure them. 
But yes, there should be a way to define the default config for TinyMCE in general, but also specific for documents and data objects. 
Marked as bug since it seems to be not working as documented [here](https://github.com/pimcore/pimcore/tree/bdc9a2dcd6d75403a3a1750c4c117fc8e1ea541e/bundles/TinymceBundle#custom-configuration-for-tinymce).
