Bug description

Starting NextCloud Desktop 33.0.2 on Linux migrates the config from ~/.local/share/NextCloud to ~/.config/NextCloud, but logfiles are still written to ~/.local/share/NextCloud after the config migration

This results in the following messages to stderr on the next start (with 3 sync targets defined):

$ nextcloud 
nextcloud.gui.application: Migrating old config from "/home/user/.local/share/Nextcloud" to "/home/user/.config/Nextcloud"
nextcloud.gui.application: Failed to move the old config directory to its new location ( "/home/user/.local/share/Nextcloud" to "/home/user/.config/Nextcloud" )
nextcloud.gui.application: Will move the individual files QList("A_sync.log", "B_sync.log", "C_sync.log")
nextcloud.gui.application: Fallback move of  "A_sync.log" also failed
nextcloud.gui.application: Fallback move of  "B_sync.log" also failed
nextcloud.gui.application: Fallback move of  "C_sync.log" also failed

and logfiles are still written to /home/user/.local/share/Nextcloud

Removing the folder /home/user/.local/share/Nextcloud while the client is closed removes these errors on the next start, but as the folder is recreated to write the logfiles there... it's back to square one.

Steps to reproduce

• upgrade a 4.x to 33.0.1 on Linux
• start and exit "nextcloud"
• rm ~/.local/share/Nextccloud
• start nextcloud again
• ls ~/.local/share/Nextccloud

Expected behavior

Migration should happen only once, logfiles should be written to the new location.

Additional info

The "create debug archive" button in Settings -> General is greyed out, debug logs could be created with "F12" but the string .local/share could not be found in any of the debug logs created.

Did I understand the pull request correctly in that you just silenced the output,
instead of making sure that the log files are no longer written to legacyDir?
