Auto merge of #24783 - jooert:unittestguidelines, r=alexcrichton

Changes the style guidelines regarding unit tests to recommend using a sub-module named "tests" instead of "test" for unit tests as "test" might clash with imports of libtest (see #23870, #24030 and http://users.rust-lang.org/t/guidelines-naming-of-unit-test-module/1078 for previous discussions).
