ConfigTest: Fix tests for getting empty config value as int

The tests were set up to expect an IllegalArgumentException when
the Config.getInt method was called with a section.key that has
not been set, or explicitly set to an empty string.

However, the IllegalArgumentException never gets thrown because
the getInt method returns the provided default ("1"), and because
there was no call to "fail" after getInt, the incorrect behavior
of the test was not noticed.

Remove the try/catch around getInt, and instead assert that the
expected default value is returned.

Found by Error Prone, which reported:

  Not calling fail() when expecting an exception masks bugs
