BUG: Explorer Plugin Does Not Search For Directories

### Checks

- [X] I have checked that this issue has not already been reported.

- [X] I am using the latest version of Flow Launcher.

### Problem Description

When searching through a tool that indexes both files and folders, it is expected that if you search for a directory and have a match, that it will display as one of the top options.

This is not what happens, however, as no matter what you enter or how you enter your search query, that specific folder that you want will never be listed in the results. It will show random files from nested subdirectories of the directory that you want, but it will never list the directory itself as an item. Because of this, it is physically impossible to search for a specific folder unless you've already added said folder to your Quick Access Links, which ultimately defeats the purpose.

### To Reproduce

1. Try searching for a directory
2. Realize that said directory never shows up in the results, add the desired directory to Quick Access Links
3. Have it finally show up in the results

### Screenshots
