MergerSite - Zite retains old merger_type permission after modifying wrapperPermissionAdd.

Step 1: Please describe your environment

• ZeroNet version: 0.7.2
• Operating system: Manjaro
• Web browser: Firefox
• Tor status: disabled
• Opened port: yes
• Special configuration: no

Step 2: Describe the problem:

I cloned GitCenter.
I downloaded GitCenter and then rewrote it to my liking in order to start my own GitCenter, called ZeroSafe.
My site however is still looking for GitCenter sites.
I've noticed that this is due to this function:

zeroPage.cmd("wrapperPermissionAdd", ["Merger:ZeroSafe"])

This adds a permission, but does not set it.
So whenever I change it, it adds another permission
and when I went a little digging I could not find any command that removes or empties the permissions.
I can't manually remove the in sites.json either and I have no idea where these permissions are stored.

Steps to reproduce:

1. Open a couple of Gitcenter projects.
2. Recreate Gitcenter, name it Newcenter.
3. Edit the following in your Newcenter site:

-- zeroPage.cmd("wrapperPermissionAdd", ["Merger:GitCenter"])
++ zeroPage.cmd("wrapperPermissionAdd", ["Merger:NewCenter"])

Observed Results:

error

Internal error: Exception('Merger site (NewCenter) does not have permission for merged site: 
18r929Hq8hE5Pi9Zf7ovMQVyn3WcGfxMgu (GitCenter)'): Merger site (NewCenter) does not have permission for merged site:

UiWebsocket.py line 80 > 238 > MergerSite/MergerSitePlugin.py line 168 > 136 > 43

sites.json

permissions: { ..."Gitcenter", "NewCenter"...
}

Expected Results:

Absention of GitCenter permissions.

Commencez par MergerSite/MergerSitePlugin.py autour de la ligne 168 et par le chemin d’appel de UiWebsocket.py autour de la ligne 80. Reproduisez la modification des permissions avec wrapperPermissionAdd, puis suivez la manière dont les permissions de merger sont stockées et mises à jour. C’est terminé lorsque la modification de la permission du wrapper ne laisse plus l’ancienne permission de merger et que l’erreur de recherche GitCenter signalée ne se produit plus.
