Fix warning about fixture files

warning: the following files do not match any of the configured `:test_load_filters` / `:test_ignore_filters`:

test/fixtures/example-umbrella-app-with-conflict/apps/app_a/lib/module_a.ex
test/fixtures/example-umbrella-app-with-conflict/apps/app_b/lib/module_a.ex
test/fixtures/example-umbrella-app/apps/app_a/lib/module_a.ex
test/fixtures/example-umbrella-app/apps/app_b/lib/module_b.ex

This might indicate a typo in a test file name (for example, using "foo_tests.exs" instead of "foo_test.exs").

See the configuration for `:test_pattern` under `mix help test` for more information.
