table-output-component not shown until analysis complete

When opening table-output-component and filling the table with the initial cache the table is not shown until the back-end query returns. For the Events table it's not an issue because the back-end query returns very quickly. However, for segment store tables of the Trace Compass trace server (e.g. IRQ latency analysis table), the query only returns when the analysis is finished. This can take a while depending on the trace size and analysis. Not opening the view and hence not providing feedback to the user is not ideal. Instead an the view should open and a feedback should be shown (e.g. analysis running).

There might be some back-end updates needed to indicate that analysis is running.
