tdf#93389: keep encryption information for autorecovered MS formats
The autorecovery data is stored in ODF, regardless of the original document format. When restoring, type detection generates ODF data, which is stored in the media descriptor attached to document, even after real filter was restored (see AutoRecovery::implts_openDocs). If real filter is not ODF, then at the save time, it doesn't find necessary information in encryption data, and makes not encrypted package. This patch adds both MS binary data, and OOXML data, to existing ODF data for recovered password-protected documents (regardless of their real filter). TODO: only add required information to encryption data: pass real filter name to DocPasswordHelper::requestAndVerifyDocPassword from AutoRecovery::implts_openDocs.
