task.transitionToTarget() does not change the target of a task immediately

[Markus Korn]

transitionToStatus and transitionToImportance have instantaneous effect on the attribute of the task, but as you can see in the attached example transitionToTarget does not, it needs the bug to reload:

In [1]: b = launchpad.bugs[123456]

In [2]: t = b.bug_tasks[0]

In [3]: t.status
Out[3]: u'New'

In [4]: t.transitionToStatus(status="Invalid")

In [5]: t.status
Out[5]: u'Invalid'

In [6]: t.target
Out[6]: <project at https://api.staging.launchpad.net/beta/bughelper>

In [7]: a = launchpad.projects["amarok"]

In [8]: t.transitionToTarget(target=a)

In [9]: t.target
Out[9]: <project at https://api.staging.launchpad.net/beta/bughelper>

In [10]: b.lp_refresh()

In [11]: t.target
Out[11]: <project at https://api.staging.launchpad.net/beta/bughelper>

In [12]: b = launchpad.bugs[123456]

In [13]: t = b.bug_tasks[0]

In [14]: t.target
Out[14]: <project at https://api.staging.launchpad.net/beta/amarok>

The problem is that the URL of the object changes (since the target is part of the URL). Not sure yet how that can be best solved.
