Trace quick access table disposal

[trancexpress]

Tracing for fail in QuickAccessDialogTest hints at a disposed table prior to updating entries in the table. This change adds tracing for table dispose to validate this.

See: #4009

The tests in QuickAccessDialogTest seem to be failing a lot with this change... I'm not sure why. All the fails are on MacOS, similar to #4009...

Unfortunately the new tracing is hard to use, without knowing which test is running (still no clue where the workspace logs are for GH jobs)...

Seems like some of the job done notifications arrive when the test is already in tearDown():

Which is this code:

		text.setText("B"); // The letter mustn't be part of the previous 1st proposal
		assertTrue(DisplayHelper.waitForCondition(table.getDisplay(),
				TIMEOUT,
				() -> table.getItemCount() > 1 && !table.getItem(0).getText(1).equals(oldFirstItemText)),
				"The quick access items should have changed");

In the standard out I see:

This seems odd, since the test waited for ~10 seconds for those computations... Here are the 10 seconds:
