Fix sd encoded table style name handling

Found this while looking into improving insertion of pages
with tables, as SdDrawDocument::InsertBookmarkAsPage uses "_"
as the rename suffix for styles with identical names but a
different content.

This commit fixes two issues:

- For import, cell styles with encoded names couldn't be found
by table styles. The reason is that styles are referenced in
ODF by encoded names, but at runtime by display names. Yet we
were searching the cell style family by encoded names. This was
already handled for sw in insertTabletemplate(), and now do the
same for sd.

- For export, table template names were encoded, but then
referenced by tables using their non-encoded names. This is
unlike the sw code that doesn't encode them, and therefore
doesn't have this problem. Looking at the schema, both
table:name attribute of a table template, and table:template-name
attribute of a table are of type "string", which suggests that
there is indeed no need to encode those names. This aligns with
the fact that table templates don't have a display-name attribute.
