Isolate hamcrest

[paulo-ferraz-oliveira]

I started this after discussing this and that, as a means to isolate hamcrest.

I ended up:

• isolating hamcrest from dialyzer -related static analysis issues,
• making for a stricter static analysis,
• broadening the OTP version scope and analysis scope of Travis CI.

This looks good. This makes xref and dialyzer emit no Hamcrest-related warnings?

(i.e. rebar3 xref = no warnings)
