Keep single redirect URI

[mlt]

Google may ask to re-validate things if Alfresco page has been opened for too long. If one navigates somewhere deep within a site, this results in corresponding redirect URI that is apparently not registered within Google Console thus resulting in Error: redirect_uri_mismatch.
Perhaps requested Alfresco path can be stored in state parameter and passed around while redirect URI set fixed, e.g., to /share/page.
