Test Expectations: Use file order as override priority. Now expectations that happen first in the file will override those later expressions. This fixes the weird conflict that could occur when we use wildcards inside the expression. e.g.: a) 6746 : *BadConfig = SKIP b) 5076 : TestSuite.Test/* = TIMEOUT Previously b) would override a) for TestSuite.Test/BadConfig and we would give the expectation as TIMEOUT because the string length of the expectation was longer. This will allow us to use short skip expressions for e.g. TSAN.
