Benefit from changes to `elvis_core`: 3.2.4 > 3.2.5 (#68)

Bump elvis_core to 3.2.2 (#62)

Prevent rebar3 crash and more output than required (#61)

This was:
1. throwing on rebar3's call to code:which, which assumes
   a return like {error, {Module, Reason}}
2. returning the values of the analysis as a term while
   also printing them to stdout

Output more context on error (#60)

* Fix our spec.s as per elvis_core and output more context on error

The test is a dumb one, not unlike the prior version of it,
but it makes sure we don't crash on function call (mimics
rebar3) and on io:format'ing it

* Bump elvis_core from 3.2.0 to 3.2.1
