tests: rename from test-config-case.t to test-config.t for centralization
Before this patch, there is no test script testing configuration
handling generally. "test-config-case.t" seems to be specific for
testing case sensitive configuration.
This patch renames from "test-config-case.t" to "test-config.t" for
centralization of tests around configuration handling.
