Saved GFF doesn't have a ##sequence-region directive

[scottcain]

Describe the bug

When using the "save track data" option, the generated GFF does not have the ##sequence-region directive. While I don't consider this a huge deal, it would be better to have it.

To Reproduce

On WormBase's staging site, see https://staging.wormbase.org/tools/genome/jbrowse2/?session=share-TtNzOW2aJV&password=pc2f1 and select "save track data" from the track menu. Observe that there is no ##sequence-region line on the top line.

Expected behavior

A line with ##sequence-region should be at the top of the GFF3 output.

Screenshots

Version:

2.4.2 from the save_track_data branch
