[FIX] Remove unnecessary permissions check on app permissions review modal

[rique223]

Proposed changes (including videos or screenshots)

Jira task: MKP-166

Removed an unnecessary check that verified if the app permissions list was an array and threw an error if it wasn't. This check has become unnecessary ever since the app permission review modal changed to show a default list of permissions in case the app happened to not have one and that's what caused those "random" undefined toasts that showed every once in a while. Demo gif:

Issue(s)

Steps to test or reproduce

1. Access the admin section and then the apps option
2. Install any app that has a 27 item(as of this PR) list of permissions
