fix PermissionsViewer 'View Role Members'

[meowpurrpur]

Closes #4192

The “View Role Members” button added by PermissionsViewer relies on the RoleMemberPopout hook implemented by BetterRoleContext. Without the plugin enabled, the popout renders without any members.

This is resolved by implementing the hook used in BetterRoleContext to acquire the RoleMemberPopout component.

I kind of overlooked the fact that BetterRoleContext needs its patch to function...

This is indeed a fix but I'm not sure if I like making BetterRoleContext a dependency of PermissionViewer

[meowpurrpur]

Ah alright, i'll look at fixing it another way

@Vendicated would the updated fix I made be better than adding it as a dependency? i don't have much experience with plugins and stuff
