Cannot connect to my Google drive, that is Google drive server connection doesn't work for me.

To reproduce:

1) enable LibreOffice dialogs;

2) select 'File > Open';

3) press button 'Servers';

4) fill in the 'Name:' text box with the name of the new server connection;

5) select CMIS from 'Type:' drop down list;

6) select Google Drive from 'Server type:' drop down list;

7) fill the 'Login:' text box with the Google user name to be used for access;

8) press the button on the right of the 'Repository:' drop down list;

9) fill in the credential dialog with the user name and password; the user name should be the same as given in step 7) above, confirm the dialog;

Nothing happens, after a few seconds the dialog regain focus and nothing else happens, e.g. 'OK' button not enabled.

Expected behavior: a few seconds after step 9) the string 'Google Drive' should appear in 'Repository:' drop down list and the 'OK' button is enabled

I checked the expected behavior by using my own values for '--with-gdrive-client-id' and '--with-gdrive-client-secret' configuration options on a libreoffice-5.0 branch built by me.
