Fix authentication issues for macOS File Provider Extension

[claucambra]

Depends on nextcloud/nextcloudfileproviderkit#22

Improve the authentication phase of the File Provider Extension by:

• Verifying account details are correct before signalling the extension is ready to perform file operations
• Reattempting authentication check if necessary due to bad connection
• Adding timeouts for said authentication check to prevent server overloading
• Properly using user and userId roles to fix LDAP authentication issues

Fixes #6783
