Update exception tests to JUnit Jupiter

Upgrade the tests in the exception package to use JUnit Jupiter as
part of the effort to remove the dependency on the Vintage Engine.

While most of these changes are drop-in replacements with no functional
benefit, there are some non-obvious changes worth mentioning.

Unlike org.junit.Test, org.junit.jupiter.api.Test does not have an
"expected" argument. Instead, an explicit call to
org.junit.jupiter.api.Assertions.assertThrows is used.

Another non-obvious change was performed in
ContextedRuntimeExceptionTest. Unlike JUnit Vintages's @Before, JUnit
Jupiter's @BeforeEach does not apply if a parent's method is annotated
with it and the overriding method is not, so an explicit @BeforeEach
annotation had to be added to ContexedTuntimeExceptionTest#setUp().

It's also worth noting this is a minimal patch for migrating the
package's tests to Jupiter. There are several tests that can be made
made more elegant with Jupiter's new features, but that work is left
for subsequent patches.
