Changeset 18686 in josm for trunk/src

Message:

See #22767, fix failing unit tests

The fix for #22767 included a new unit test, which caused a cascading failure.
The first step of the fix included removing the destroyed dialog from the
MapFrame. Unfortunately, MapFrame#removeToggleDialog did not properly
remove the ToggleDialog -- it called DialogsPanel#remove(Component) with
the ToggleDialog as an argument. Since the DialogsPanel never adds the
ToggleDialog as a direct subcomponent, this was effectively a no-op.
