[FIX] clipboard: paste without asking permission

[LucasLefevre]

Description:

Since 825f0176d4e083f246f1775, copy and paste some cells in the spreadsheet requires the user to allow reading the OS clipboard.

It's annoying, and if the user dismisses (or blocks) the popup, copy-pasting doesn't work anymore (the permissions need to be reset). Task: 4138195
