Cleanup configuration spec (#680)

* Clean up clearance configuration spec

Remove unnecessary before hook and maintain consistency on setting
up clearance configuration for each test example.

Why:

In the configuration spec, there are some before hook where we're
basically setting up nothing, but defaults.

There is no consistency on setting up configuration, some example
using before hook and others are not, some are using inline block
and others are using multi-line block although it sets a single
clearance configuration.
