Disable accessibility-dump test (aka a11ytests)

It works by comparing a dump of the a11y widget tree with a known-good
version, but that seems to vary unpredictably according to some unknown
factor. Upstream's CI currently disables all the a11y tests, so we can't
expect this to be reliable.

+
+This test seems to be unreliable, with its results depending on
+unknown environmental factors. Upstream disable it for CI purposes,
+so we should probably do the same.
