Image alias metadata not removing on clearing liip_imagine filters while binary files are actually removed.

Steps:
1) Create image object in admin panel
2) Render the image in a template applying any image alias
3) Open page and observe it's loaded and image rendered
4) Clear image aliases with "liip:imagine:cache:remove --filters=my_filter" command.
5) Open the same page where image should be rendered
Actual result: Binary not found exception
Expected result: Image alias file recreated and rendered
