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

[jrfnl]

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.
