Description:
Modifying an existing LibreOffice installation to remove some already installed dictionaries will leave stubs for the extensions installed in both the Extension Manager and the Options dialog.

Steps to Reproduce:
1. Install LO with default settings (this will include Russian and Hungarian dictionaries)
2. Open LO once, make sure all works fine.
3. Modify the installation and remove the Russian and Hungarian dictionaries from the setup options of the MSI installer. -- see attachement modify_installation.png
4. Open LO again and check the Extension Manager and Options dialog.

Actual Results:
The extension manager shows dict-ru and dict-hu as two stubs for the extensions that were previously removed. -- see attachement extensions.png
The Options dialog also shows the Hungarian Sentence Checking and the Grammar Checking (Russian) as empty pages. -- see attachement options.png

Expected Results:
The extensions should not have been there, they should have been removed entirely.
The Options dialog show not show any options regarding the Hungarian and Russian pages under Language settings.
