tdf#153642 ucb: fix broken save with cached DAVOptions

Trying to save a document within the lifetime of the
cached connection, e.g. re-save within a few seconds after
the first and successful save failed with an error message
in the case of Vibe 4.0.6 WebDAV server. Waiting 5-10 seconds
after the last try was the only workaround to re-save the
document.

Details: aDAVOptionsException in Content::getPropertyValues()
removed the isClass1 bit of the cached DAVOptions of the
same TargetURL (note: of the folder of the WebDAV document).
This disabled the DAV detection part of Content::getResourceType(),
and later the correct HTTP redirect for the DAV connection.
Fix this by keeping the cached bit in that case, too, when the
added connection has a different lifetime, than the cached one.

Follow-up to commit 30ca48f4dc
"tdf#152493 ucb WebDAV: fix upload using HTTP 1.0 fallback".
