Fixed failing test in about_asserts.rb

* Learned that assert has a second optional
argument that contains additional
information to help figure why the test is failing

*This can be helpful in debugging why a test failed

* Passing boolean options to assert will pass
or fail based on whether the
boolean is true or false.

*Assert_equal gives better error message when
the test fails, i.e. "____ expected but was ____"

*I like knowing what was expected instead of
"assert failed, no message given". Not that helpful
of an error message.

* Sometimes a value is just a value

Fixed failing test in about_asserts.rb

*Learned that the assert method simply asks if
the argument it is passed is true.

*assert true # => posses

*assert false # => fails
