Only show submit type in change view for open changes

Submit type is per project, not tied to specific changes.

If the project's submit type is changed after a change has been
merged, the displayed information will not be correct; it will
show the current merge type, which is not necessarily the one that
was used at submit time.

If a change has been abandoned, the submit type is not relevant.
