Snippets title-column always links to "edit" page

[LCMJ21]

Issue Summary

Even if a user does not have the "change" permission, the SnippetViewSet still renders a link to the EditView, which then results in a permission error for this user. For example, we often use SnippetViewSet and use inspect_view_enabled = True and only allow inspect.

Falling back to the inspect view, if it has been enabled, and not defining a link if none of the others are available, seems a good way to solve it.

Steps to Reproduce

1. Add a wagtail_hooks.py and register a SnippetViewSet
2. Create a custom ModelPermissionPolicy and make user_has_permission return false if action==change
3. Redefined the permission_policy property in your SnippetViewSet to use your ModelPermissionPolicy
