Validation on upload does not respect previous "ignores"

[AM909]

In r5181:

When using the validator, if you select a particular item from the list of reported errors and click the "ignore" button, it stores these exceptions for the future, and will not show that particular error for that object when you run it again.

However, when you upload, and it runs the validator, it ignores these previously stored exceptions, and reports those "errors" again.

The validator should respect the stored exceptions, regardless of how it is called.
