fix: URL with hash sign in after_verification_return_to stays encoded

[martinboehm]

Fixes a problem that when after_verification_return_to parameter containing hashtag # is specified, the server redirects to URL containing hashtag in URLEncoded form %23.

For example, specify after_verification_return_to=/foo/kratos#abcd

Incorrect behavior (before the fix):
The verification flow redirects to /foo/kratos%23abcd

Correct behavior (after the fix):
The verification flow redirects to /foo/kratos#abcd

Fixes #2068
