Remove usage of `should` in test method names betterspecs.org/#should

It seems like the test uses a lot of `should` instead of just stating what it does, and what the purpose of the test is.

betterspecs.org/#should is properly the best description to why should is disallowed. Also its a best practice to not use should when speccing .
Simple way to remember this: I have, it has. :)

'Have' is almost only used when referring to a 1 first or second person; I have, we have.
Referring to an object to pointing to someone is always 'has'; it has, my object has, she (pointing) has.
