InvalidBatchSizeErrorView reports configured maximum batch size but this can be overridden.

[Henning Eggers]

For example, POFileTranslateView uses POFileBatchNavigator which overrides the max_batch_size property of BatchNavigator to enforce a lower value. The ErrorView should use that same property instead of getting it from the config directly.

Really, lazr.batchnavigator should propagate the maximum value in the exception but it only returns an error message which contains this value. So without changing anything in lazr, I'd propose to display that error message. Here is a fix that would do that, I can land that today.

The error message from lazr is:
Maximum for "batch" parameter is 300.
