This test verifies that common contraction is not marked as misspelled when autocorrection is off.

Step 1: Bring up contextual manual, and uncheck "Spelling and Grammar -> Correct Spelling Automatically" and "Substitutions -> Text Replacement".

Step 2: Type "this wasn't", and verify that "wasn't" isn't marked as mispelled.

Step 3: Restore the settings in contextual manual, otherwise it may affect the result of other autocorrection related tests.
