Save options widgets deleted

[caillancm@…]

The following bug report has been submitted:
Platform:        Linux-5.3.0-51-generic-x86_64-with-debian-buster-sid
ChimeraX Version: 1.0 (2020-05-08)
Description
This is an update to bug #3175.

After a model is fitted into density, the save dialogue won't work. This doesn't happen with every model and map, but the commands in the log could repoducibly trigger it on my system.

Hi Caillan,

Actually the problem is that the save dialog only works the first time. Subsequent uses fail with the error you saw. Again,sorry! :-(
