Accessing an invoice from the Invoice overview causes an IllegalStateException

[czarnecki]

On the update-major-dependencies branch, if you try to access an invoice from the invoice overview an IllegalStateException is thrown. This happens because the InvoiceDetailsPage constructor creates an AjaxLink that overrides onConfigure() without calling super.onConfigure().
We need to check if this issue was introduced in that branch, or if it's already present on the current main.
