Client certificate file can't be cleared
Bug description
Once a Client certificate file is set for an Account, it can not be removed.
After clearing the entry Client Cert File in Accounts dialog and closing the dialog, the file name is again displayed when the dialog windows is opened.
The "client_cert" preference can be removed only using Advanced Configuration Editor.
Steps to reproduce
- Try to set the attached "lo.p12" client certificate as Client Cert File.
- Close the "Accounts" dialog
- Open the "Accounts" dialog
- Clear the file name from Client Cert File
- Close the "Accounts" dialog
- Open the "Accounts" dialog, the file name is still there
