Problem description:
Writer doesn't honor changes of bibliography database entries when updating a bibliography. It seems that Writers saves the biblography entries in the local document even if "from bibliography database" is selected when inserting a bibliography entry.

The strange thing is that if you insert a reference to the same entry of the biblio DB after changing it, LO Writer offers to insert the Bibliography Entry _based_ _on_ _document_ _content_. Obviously, Writer saves the biblio entry in the local document instead of referencing the biblio db.

Steps to reproduce:

Method 1:
---------
1. Create a new writer document;
2. Insert a new bibliography entry using menu "Insert" -> "Indexes and Tables" -> "Bibliography Entry"; make sure that "From Bibliography database" is selected.
3. Insert a new Bibliography using menu "Insert" -> "Indexes and Tables" -> "Indexes and Tables...", Type "Bibliography". Writer should insert a Bibliography with one entry.
4. Edit the bibliography database: either using Menu "Tools" -> "Bibliography Database", or by hitting F4: make sure to edit the bibliography entry you've inserted in step 2;
5. Update all fiels using Menu "Tools" -> "Update" -> "Update all".

or 

Method 2:
---------

1. Create a new writer document;
2. Insert a new bibliography entry using menu "Insert" -> "Indexes and Tables" -> "Bibliography Entry"; make sure that "From Bibliography database" is selected.
3. Edit the bibliography database: either using Menu "Tools" -> "Bibliography Database", or by hitting F4: make sure to edit the bibliography entry you've inserted in step 2;
4. Insert a new Bibliography using menu "Insert" -> "Indexes and Tables" -> "Indexes and Tables...", Type "Bibliography". Writer should insert a Bibliography with one entry.

Current behavior:
- Method 1: The Bibliography isn't updated using the most current data from the Bibliography DB.
- Method 2: The inserted Bibliography uses the initial bibliographic data of the biblio entry instead of the current data.

Expected behavior:
- Method 1: The Bibliography should get updated, reflecting the changes in the biblio DB.
- Method 2: The inserted bibliography should use the current data from the biblio db.
