Backspace at the start of the second of two consecutive tables merged their
anchor paragraphs: Story::delete kept one table id, the other table was
dropped and the paragraph held two anchors. Pasting a table next to an anchor
replaced the existing table the same way, and pasting several paragraphs
right before an anchor left its table unreferenced. Saving succeeded;
reopening failed with "paragraph must hold exactly one anchor".
fix_tables now splits a table paragraph that holds further anchors, so every
anchor gets its own paragraph again. delete and insert_story tell it which
table each surviving anchor belongs to (fix_tables_with), and insert_story
fixes tables up once after the whole paste instead of after every run.
Regression tests in doc (Backspace between tables, deleting the middle of
three, paste before/after an anchor, paragraphs pasted before an anchor) and
engine (text.delete and edit.paste through commands, then a file round-trip);
all failed before the fix.
