Possible bug in upgrade script

[tmkarlsen]

When updating library versions on H5P-resources, some libraries experience more or less known errors. Documentation Tool has the most severe error where both of these errors seem to occur:

1. The H5P title is overwritten with data from the next input field (seems like a known and willing change)
2. The existing data within H5P "Metadata" is dropped

I have testet uploading an H5P with an older version to H5P.org and the result is as seen above: https://h5p.org/node/1247114
For more screenshots showing the before and after, please visit cerpus/Edlib#455

These are the ones documented so far:

Single Choice: error 1 (title is overwritten)
