MeshCentral/meshuser.js
Josiah Baldwin c50b3c0d26 Fix bug in addusertousergroup 
Fix obscure bug when the last user added in list of addusertousergroup was an unknown user causing the server to crash.

Also updated the group update message of same to display all users added, rather than only the last one in the list.
