function RecipeMultipleModulesConfigStorageTest::testSimilarModuleNameIsolation

Tests that modules with similar name prefixes are correctly isolated.

The 'system' and 'system_test' modules share the string prefix "system" but must be treated as entirely separate modules. Configuration is routed by the part of the config name before the first dot, so 'system.site' belongs to the 'system' module and 'system_test.settings' belongs to the 'system_test' module.
