Filters are not called on uploads folder

**Describe the bug**
Applying a filter on `"/uploads"` folder, does not get called.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a sample filter with a `std::cout` inside.
2. Make sure the uploads folder is set in `config.json`.
3. Add a `"locations"` config entry:
```json
{
"uri_prefix": "/uploads",
"filters": [ "YourFilter" ]
}
```
4. In the HTML file, add an `` tag.
5. Set the image's src to a file or a random name within the uploads folder. (e.g. `src="/uploads/random.png"`)
6. Run the application, no output will be observed when opening the HTML file page.

**Expected behavior**
The filter should get called.

**Additional context**
Alternatively, we could do this with Sync AOP, but we would have to always check for the path.
