NOTE records are not generated or modified with correct GEDCOM

[Jefferson49]

By default, webtrees-API generates/modifies a record with the following GEDCOM content:

1 NOTE A record created by the webtrees API.
1 NOTE Read description about line breaks.

However, NOTE records have a different GEDCOM structure:

0 @X1@ NOTE My text

In this case, webtrees-API creates wrong GEDCOM

0 @X1@ NOTE  
1 NOTE A record created by the webtrees API.
1 NOTE Read description about line breaks.
