Merge #11025: qa: Fix inv race in example_test

faa76d1b7 qa: Fix inv race in example_test (MarcoFalke)

Pull request description:

  There have been intermittent test failures on this script.

  ```py
    File "./test/functional/example_test.py", line 216, in run_test
      assert_equal(block, 1)
  AssertionError: not(2 == 1)
  ```

  Probably the simplest way to fix them is overriding the `on_inv` method, so that no "colliding" getdata for the blocks are sent out.

  Additionally, all getdata are now sent in a single message.
