PHPCS: fix up the code base [6] - multi-line function calls

Fixes relate to the following rules:
* Each argument in a multiline function call should start on a new line.

Note: in the (near?) future, multi-line arguments in function calls will also be prohibited.
This will impact this code.

The choice for the future is:
* Either change the closures to full-blown methods.
* Declare each before their respective function call, assign them to a variable and pass the variable to the function call.

Note: this commit will be easiest to review by ignoring whitespace changes.
