tdf#132514 DOCX import: fix lost table style with footer

Table paragraphs collected for table style processing
were mixed when both body text and footer contain tables,
i.e. clearing paragraph vector at processing the first table
resulted missing paragraph vector and table style processing
for the other one.

Now tables in footer, also nested tables collect their
paragraphs in separated table paragraph vectors.

Regression from commit 6c5da2cd7af5c2d90e4d8e9635ba8c9989c87923
(tdf#119054 DOCX: fix not table style based bottom margin).
