Unnecessary extra tag(s) when saving GPX file

Issue #479 resolved
wthaemelt created an issue

The attached (abbreviated) GPX file was created with the Python package gpxpy. It is loaded without any problems in QMS.

The GPX file has by an unknown reason a harmless additional <link> tag in the track header (and tags of the same form in the trackpoints).

When saving the project loaded from this file with the menu entry Save as GPX 1.1 w/o ext... the new GPX file has a lot of additional and unnecessary (but harmless) <link> tags in the track header (the number of additional tags seems to be equal to the number of trackpoints(?)).

Could the creation of these unnecessary tags be suppressed?
