Shibboleth:  Fix our implemtnation of CookieJar::deleteCookie

It was deleting too many cookies.
That function is virtual in Qt5 and is used when adding cookie.
But some Shibboleth have several cookies with the same name, and we need to keep them.

Our implementaiton was meant to delete all the shiboleth cookies when we want to log out
Revert "Folder: Don't blindly trigger sync on first EtagJob result"

We need to do a sync even if the etag was empty because we do not know
if this is because the etag really changed or because it was new.

Also, some part of the code rely on this fact to schedule a sync.

The fact that there is two sync with 30 sec at the beginning is not
a big problem, because we also need to do the sync the put the directory
etag in the db.

This reverts commit 1c001ee13865ceb4598c989e5308d27aead74540.
Propagator QNAM: Fix resuming
