Fix two issues with textlines in PAGE XML files

[stweil]

Both issues were found while extracting line GT for the training of Tesseract.

While fixing those issues manually, I noticed more severe issues in both files:

• There exists a textline with the text "jeden und", but the words give the correct transcription "Bey allen".
• The textline "auch allhie Paulus von allen geiſtlichen ret" should be "ret auch allhie Paulus von allen geiſtlichen". While the word order is correct on the word level, it is wrong on the line and region levels.

In the worst case that might be systematic errors which occur often. Which tools were used to produce the buggy output?
