Indexer v3 Rewrite: _saveIndexKey now really writes on the desired line

Now _saveIndexKey inserts empty lines when the index isn't long enough.
This is necessary because the page ids are taken from the global page
index, but there is not every page in the metadata key specific index
so e.g. line 10 might be the first entry in the index.
