Prompt user before discarding table

[Harry Jeffery]

In the new Refl UI, if the user opens an existing table or tries to start a new table they will lose any changes made to their current table. The UI should prompt the user, asking them if they wish to save their changes first.

Refs #10372 Add unit tests for prompt before discarding

Changeset: 31ebbbcba8ec10badac792e1a87e6c89465824dd

[Harry Jeffery]

Testing

1. Start a new table
2. Make changes
3. Try to start a new table. You'll be asked if you're sure you want to discard your changes.
   • Verify both responses behave as you would expect
4. Save
5. Try to start a new table. You should not be prompted, it should just work.
6. Make changes again.
7. Try to open a table (such as the one you just saved). You should be prompted about unsaved changes.
   • Verify both responses behave as you would expect

And the old favourites:

• Verify unit tests are passing
• Inspect code
