Update to ticket with deleted component doesn't send emails.

[James Dio]

If you delete a component which still has tickets associated to it and you then update the ticket, an error will be generated in your log files:

Traceback (most recent call last):
  File "build/bdist.linux-i686/egg/announcerplugin/api.py", line 356, in _real_send

ResourceNotFound: Component component1 does not exist.

No notification emails are sent.

I have created a patch for this. Python is not one my "primary" languages so if you want to use the attached patch, look it over first, however it has resolved the issue for me.

In the future, please make sure that you diff doesn't contain tabs, but only spaces. And also that it doesn't contain different newline characters then the original source. This can be setup in your editor if it is a reasonable editor.
