ENOENT: no such file or directory, open '.git/COMMIT_EDITMSG'

When the .git directory is not in the same path than your execution directory, this error is thrown

    at Error (native)                                                                                                                                                                                                                             

in the example, the .git directory is /Users/javier/Documents/tdaf-pibot/.git but the node project with the package.json is in /Users/javier/Documents/tdaf-pibot/paco (one directory inside)

I think this can be solved by executing git rev-parse --show-toplevel for obtaining the current git directory and make an absolute path in https://github.com/marionebl/conventional-changelog-lint/blob/master/source/library/get-messages.js#L29

WDYT?
