xfd: CfD/S C2F should tag the page with {{subst:cfm-speedy}}, not {{subst:cfr-speedy}}

Requested by Jlwoodwa at https://en.wikipedia.org/wiki/Wikipedia_talk:Twinkle#CFD%2FS_merging

Making this change would better follow the instructions at https://en.wikipedia.org/wiki/Wikipedia:Categories_for_discussion/Speedy#C2F:_One_eponymous_page, which specifically states that {{subst:cfm-speedy}} should be used

The template params look the same, so shouldn't need to mess with that.

The line of Twinkle code that needs to be modified is params.tagText = '{{subst:cfr-speedy|1=' + params.cfdstarget.replace(/^:?Category:/, '') + '}}\n';. This should be split into something like if ( isC2F ) { } else { }
