[CLEANUP] Reformat the code a bit

[oliverklee]

With the latest version of PHP_CodeSniffer, we can have boolean operators
in the middle of a line as well. This allows us more liberties with code
formatting in order to make to the code more readable.

I'll have a look into the build failures.

[oliverklee]

Strange. There is no composer install happening on the failed jobs.

Yes it's more readable. We've been round this if a few times. I wish I'd written it better in the first place! (But, you live and learn 😒)

I've restarted Travis for the failures. Sometimes Travis randomly fails to set up the environment correctly. Odd that the failures were all PHP 7.0, which looks less like random failure than a potential issue. Watch this space...

It's still not installing any of the 'dev' dependencies. Travis itself is broken. Sigh.

Repushed. Hopefully, the build will be green now.

This one is. There's another random failure on master that I've restarted (and now succeeded).
