Update player.js quick bodge fix for #2137

[raszpl]

#2137

do nothing if we fail to grab video element in time

[ImprovedTube]

should've merged #2157 already

[ImprovedTube]

if(!video) {console.log("no video - no pause"); return;}
or retry after some ms?

---

(can also likely undo the if (!ImprovedTube.autoplayDeniedOnce) as said in the other tread)

that one just made the code look nicer, didnt change functionality

definitely this :) Iv been running my local copy with
//ImprovedTube.autoplayDeniedOnce = true;
for ~month now with no ill effects. I believe the source of users clicking on video multiple times and not getting it to play was due to #2177

if(!video) {console.log("no video - no pause"); return;} or retry after some ms?

Retry might be a bad idea on events, a lot can change between triggering and trying again, like new page loaded in the mean time.
