Unset reference variable after looping by reference for administrator/modules/mod_[a-z] and hathor admin templates

[zero-24]

• When looping by reference, reference variable is not unset at the end of the loop.
• and a bit CodeStyle

see: #5482

@zero-24 Is this something to test or does it need review by PLT?

[zero-24]

Thanks @waader no we can't test this. And it is no bug it is more a bad practice.

@ggppdk (at: #5482 (comment)):

Again this is not a bug, just a very dangerous practice not to unset the variable that references the array of the loop.

or does it need review by PLT?

Yes it needs only a decision / review by the PLT to remove this bad practice or not. So nothing to test here. Thanks! 😄
