Bug: Workbench Lens - Group's permission for workspace

[FreeCutter]

Bug repro

• User_1 is on tier 'Peer' and set up a public organizsation (Orga_A) with default group 'Everybody'
• In Workspace_A (of Orga_A) permission of group 'Everybody' is set to 'read'
• User_2 (on tier 'Solo') become member of Orga_A as well as group 'Everybody' (for claritiy reasons: User_2 is not member of Users in Workspace_A)
• User_2 is logged in to Lens via FreeCAD Workbench/Add-on Lens
• User_2 opens a new file in FreeCAD
• User_2 runs 'Ondsel Lens > Workspace > Workspace_A > Add > Add current file' to save the current file

Expected result:

• User_2 is able to save the file in the local sync folder
• User_2 is not abel to sync/upload this file with Lens Workspace_A

Actual result:

• User_2 succesfully saved locally and the procdure uploaded new file to Workspace_A
• Stage of new file is given as (Synced) in Lens Add-on
