tdf#130707 xmloff: survive <text:database-display> in editeng text

Regression from commit 28d67b792724a23015dec32fb0278b729f676736
(tdf#107776 sw ODF shape import: make is-textbox check more strict,
2019-08-26), now that we correctly identify what shape text to import as
"textbox" (Writer TextFrame) and what to import as editeng text, there
are documents out there that try to import mailmerge fields into
editeng-based shape text. Fix missing error handling there.

Note that the error is not just silently ignored, we do insert the field
result into the shape text, existing code provides this already.

(cherry picked from commit 790ab54d7232d232ba84f17f285d4639ddba80d5)
