morebits: Use custom message for spamblacklist

[Amorymeltzer]

Restores custom message removed in #707. Custom messages as specified in MediaWiki:Spamprotectiontext and MediaWiki:Spamprotectionmatch get inserted into the response, which can lead to absurdly lengthy wikitext messages in Twinkle (see #707 (comment)).

Thanks for reporting this, @siddharthvp

Live on testwiki in case anyone wants to test, but it seems to get me the response I want, so I'll push to enwiki in ~hour or so if no issues.

[siddharthvp]

This is the message I see currently on testwiki:

Seems completely different from what you wrote. Didn't try investigating why, through.

@siddharthvp Did you use revert or something else from fluff? This PR just tackles morebits, I believe what you're noticing is due to what you and I were talking about in #707, namely that since fluff uses Morebits.wiki.api and not Morebits.wiki.page nor does it provide an onError fallback, we end up with this.

We can either duplicate the morebits stuff in an additional fluff callback (quicker, worse) or convert to Morebits.wiki.page (better).

I used CSD, specifically tried to nominate the page for G12 deletion specifying copyvio source as a spamblacklisted url.

[Amorymeltzer]

Try again? Works just fine for me, same thing.

[siddharthvp]

This time, tried to PROD the page with reason http://areallyevilsite.com . Same result:

Also tried after clearing browser caches and cookies. Anyway, I guess this error text is also fine howsoever it is coming :)

But another bug is revealed here as you can see: placing of {{old prod}} succeeded w/o the prod being added :(

[Amorymeltzer]

Do you have some customjs loading or something? I get the correct message when I try to prod a page... And yes, same issue with the old prod 👎
