Import-archives are missing username (Sync 1)

[lachko]

After importing data from a json archive the username disappears for the user that exported the data. After looking deeper into this. I see a difference in the user-profile json between records
On the left a record that contains the username and on the right how the record looks after data was imported for this user from a JSON export

To make the import work I've modified the map function in the import-archives.bin.js file. Note the bold below:
.map(row => {
if (row.doc.collection !== 'TangyFormResponse') return
if (row.doc.form && row.doc.form.id !== 'user-profile') {
row.doc.items[0].inputs.push({
name: 'userProfileId',
value: userProfileDoc._id
}, {name: 'tabletUserName', value: archive[0].databaseName})
}
