Wrong correlate to gpx behaviour (use an old gpx file version)

[StephaneP]

What steps will reproduce the problem?

1. Load the images and the track.gpx file you can found inside the attached samples archive
2. correlate the images with the gpx (offset is 00:00, enable override position for image with geo location in exif data)
3. Convert the gpx to a data layer
4. add a point to make a < instead of the straight line
5. export this layer to a gpx file, and overwrite the existing track.gpx
6. Start a new image correlation, click on open another gpx, select track.gpx and correlate (enable override position for image with geo location in exif data)
7. it should be ok.
8. drag and drop the track.gpx on Josm
9. convert the gpx to a data layer and edit the center node to transform the < to a >
10. export this layer to a gpx file, and overwrite the existing track.gpx
11. Start another image correlation, click on open another gpx, select track.gpx (enable override position for image with geo location in exif data)

What is the expected result?

The images should be correlated on the > gpx track.

What happens instead?

The images seem correlated with the previous gpx (with the < instead of the >)

Please provide any additional information below. Attach a screenshot if possible.

I had this bug from time to time when I was editing my gpx files to fix some positions, but it was difficult to create the correct steps to reproduce it.
It seems Josm keep the previous versions in memory, and don't use the new version.
