[ty] Add evaluation test for auto-import including symbols in current module

This shouldn't happen. And indeed, currently, this results in a
sub-optimal ranking.

+# This is meant to reflect that auto-import
+# does *not* include completions for `Kadabra`.
+# That is, before a bug was fixed, completions
+# would offer two variants for `Kadabra`: one
+# for the current module (correct) and another
+# from auto-import that would insert
+# `from main import Kadabra` into this module
+# (incorrect).
+#
+# Since the incorrect one wasn't ranked above
+# the correct one, this task unfortunately
+# doesn't change the evaluation results. But
+# I've added it anyway in case it does in the
+# future (or if we change our evaluation metric
+# to something that incorporates suggestions
+# after the correct one).
