Required rights don't restrict edit rights

Steps to Reproduce:

1. On a document, enable required rights and enforce script right.
2. Try editing the document as a user without script right.

Expected result:

Editing isn't possible as right is denied.

Actual result:

Editing is possible.

This happened due to a bad merge in https://github.com/xwiki/xwiki-platform/commit/5f98bde87288326cf5787604e2bb87836875ed0e#diff-4b512565969c065fc1d2a844b43326e0c41d76cb31084bcb012e1f0219d17b97L164 and wasn't detected by automated tests as there were none.
