tdf#130274 sw_redlinehide: fix ChgAutoCorrWord() if replaced text ...

... is fully deleted.

This crashes on English text with 'i'->'I' substitution.

The assumption that there's some part of the found text that is not
deleted is only correct for the case where tracked changes are hidden,
but not when they are shown.

(regression from 9926ea7dd07f1f3d012ddf97941a42bb7fa5717d)
