`AsyncTAPJob` makes unnecessary network calls in property getter.

It looks like most of not all the mutable properties of the class `AsynTAPJob` make network calls to update the job info. Most of the time this seems an unnecessary overhead. At the very minimum, the code could be changed to avoid the `_update` calls if the job is in a final state, in which case the remote call is redundant.

Start by locating the AsyncTAPJob class and reviewing its mutable property getters and _update calls, then inspect any existing tests for job state and remote updates. Done means final-state getters avoid redundant network calls while non-final jobs retain their current update behavior, with tests covering both cases.
