[TYPO3-core] RFC: is_array check extension manager

[Michael Stucki]

No because he loops over $conf['constraints']['conflicts'].

$conf['constrains'] can be an array while still there might be no 
$conf['constraints']['conflicts']! So checking this first using isset is the 
only right thing to do.

Please double-check such tiny issues before writing to this list.
