Removed redudant call and dom modal clean up

[JeremyFreiburger]

Resolves #3512

The problem was opening a modal on the label map reinitialized the panorama every time creating too many web gl elements. I also have to remove the code to remove the modal because I think it is interfering with bootstraps garbage collection/reusing modals.

Before/After screenshots (if applicable)

Testing instructions

1. I tested pretty thoroughly, for each label type, validation type, and other data imported to make sure that it is the panorama that is creating too many webgl elements. When I only remove the reset call the problem still occurs.

Awesome!! Does removing the call to resetModal() cause any issues? Is all the data getting updated to the new label without the resetModal call?

And since this code is used in lots of places, I'm going to list all the places I can think of here. Can you check each place to see if it's an issue there on develop, and then make sure it's fixed in any places where it's an issue?

1. LabelMap
2. Admin page, "Map" tab
3. Admin page, "Contributions" tab
4. Admin user dashboard at /admin/user/\<username>
