Refactor getDOM to use a pointer for the optional context

It's possible to call getDOM without a contextual task.  Previously,
this was done by referencing a "dummy" task which necessitated a way to
distinguish such dummy tasks.  This switches to using a pointer and
treating the NULL value as meaning there is no context.

Note that this cannot use `std::optional<&Task>`, as optional does not
support reference types.
