Prolbem with jquery func extractor

[fxa]

Retire.js version: 6.14.5

node version: 10.21.0

Type: Bug

Description: in the repo json the func extractor jquery.extractors.func[0] is incorrect. Current value: "(jQuery || $ || $jq || $j).fn.jquery". It is clear, what is intended: if one of the 4 exists, use .fn.jquery. But that does not work! Lets say, jQuery is not defined, but $. Then the browser will throw a ReferenceError, because jQuery is not defined.

Steps to reproduce

• open a browser
• browse to https://retirejs.github.io/retire.js/
• open console in developer tools (F12)
• jQuery and $ are defined (just test it)
• enter "delete jQuery" (jQuery now is not defined, but $ still is
• enter "(jQuery || $ || $jq || $j).fn.jquery" -> result: ReferenceError

Expected behaviour: -> result: (currend jQuery version, for now "3.4.1" (btw, that should be retired by github.io ;-) ))

That could be related with https://github.com/RetireJS/retire.js/issues/314.

Btw I think all funcs should be written, that no exception should be thrown I dislike exception driven development and think, it is a bad pattern

I think, correct would be "(typeof jQuery !== 'undefined'? jQuery : typeof $ !== 'undefined' && $.fn ? $ : {fn: {jquery: null}}).fn.jquery" remarks:

• I have never seen $j or $jq, so I ommited it
• $ is problematic. E.g. my chromium has defined $ per default, but without $.fn
