[wikimedia/fundraising/crm/civicrm@master] HACK: show cancel button for recur records with no processor

https://gerrit.wikimedia.org/r/489107

@Eileenmcnaughton That hack should get the button back, but I haven't tested whether the button works. A more correct alternative fix is detailed in the commit message.

@krobinson and @MBeat33, we got a quick-n-dirty solution out there, but we haven't tested it on a real live subscription yet. Please let us know if it's working!

Actually it's not deployed yet - I've just merged it through to deployment but won't deploy now since I don't want to 'deploy & run' - @Ejegg can you deploy tomorrow?

@Ejegg @Eileenmcnaughton I'm not sure if this is deployed yet or not, but today the Contributions tab in a donor record is Civi won't open - no error message, just completely blank. Another agent, Seilo, flagged this to me, and it's the same for me. So at present we can't see any donation records, or the recurring tab to test any fixes. Yesterday we could see the records, but the 'cancel' tab was missing, now we don't have any visibility into contributions.

You're probably aware and this is likely related to what you're doing, but just as an FYI.

@krobinson sorry! I deployed something last night without testing it well. I've just pushed out a different version that should show actually the cancel button rather than breaking the whole tab

Thanks @Ejegg! I believe I just successfully cancelled a donation, so think we're all good :) Thank you!
