Add missing calls to fail() when exceptions are expected to be thrown

[Pokechu22]

Fixes #106. Without this, the test could pass if no exception is thrown, in addition to the wanted result of a matching exception being thrown.

fail() is now called before any catch in test code, as verified by grep -B1 -r catch src/test/java:

src/test/java/com/mojang/brigadier/arguments/DoubleArgumentTypeTest.java-            fail();
