Steps to reproduce:

• Create a some issues on a given project, they should stay in the Open status
• In the issue navigator, perform a search for all issues in the Open status
• Save this search
• Add the Filter results gadget to a dashboard and select the filter created in the previous step
• The issues will be displayed in the gadget
• Now, go to the Statuses Administration session
• Rename the "Open" status to "test status"
• Go to the dashboard again. The gadget will break with the following message:

The selected filter filter-16550 has an error: The value 'test status' does not exist for the field 'status'.

If you take a look at the workflows, everywhere the status Open was used, it was replaced to the new value "test status", but the filters remain with the old name and break.

The filter should save the status ID instead of the Status name, and it shouldn't be necessary for the user to do that.
