Snippets: Redirected to invalid URL after cancellation

Summary

After clicking "Cancel" upon creation of a Snippet, the user is redirected to an invalid URL.

For example:

https://gitlab.com/ddavison/sockpuppet-test/-/snippets/ddavison/sockpuppet-test/-/snippets

instead of ...

https://gitlab.com/ddavison/sockpuppet-test/-/snippets

Steps to reproduce

1. Navigate to a Project
2. Click "Snippets" from the Project menu
3. Click "New Snippet" button
4. Click "Cancel"
5. Confirm navigation away from New Snippet page

Example Project

https://gitlab.com/ddavison/sockpuppet-test/

What is the current bug behavior?

The URL redirects to https://gitlab.com/ddavison/sockpuppet-test/-/snippets/ddavison/sockpuppet-test/-/snippets

instead of https://gitlab.com/ddavison/sockpuppet-test/-/snippets (It appears to duplicate the path)

What is the expected correct behavior?

Redirection goes to /<user_or_group>/<project>/-/snippets
