Bugfix: Remove Short Array Syntax and Fix (Minor) Recent Merge Issues

[robfrawley]

Remove accidental use of short array syntax in my PR that created .php_cs.dist

@antoligy Somehow, your php 7.1 travis addition passed its build on your PR and only now fails, informing us after-the-fact that we need to update the conditional to exclude mongo on 7.1 too. ;-) IDK why...

@lsmith77 I included the above fix in the PR as it seems like an awfully small change to justify its own submission.

@antoligy Ah, figured it out. The second half of the mongo conditional in the old travis file was broken, (as in, it was invalid SH), which is the only reason mongo wasn't included for 7.0 based builds prior (not because, as one would expect, the conditional was evaluated properly).

With my fixed travis file merged #792 acting in combination with inclusion of 7.1 in your #787 with no check, caused the interesting case of your PR being green, and then our merged code being red.

All is well though, should be fixed!

Nice catch, cheers for fixing it!
