Financial type not shown if disabled

If you disable a financial type, the respective field in the contribution view is empty. I can probably provide a patch for this, but I wanted to make sure that this is not the intended behaviour. From my point of view, a disabled financial type should not be available for active use (e.g. creating or edition contributions), but the information should still be available.

To reproduce (e.g. on the demo) do the following:

1. Find all contributions
2. Select one and click "view"
3. There is a row "Financial Type"
4. Go to "Administer -> CiviContribute -> Financial Types" and deactivate the financial type of your contribution
5. Reopen / reload the contribution view
6. Observe that the row "Financial Type" has now no value. It should list the (deactivated) financial type, ideally with the information that it is deactivated.
