Drop unused canvass feature

Description & Issue number it closes

The canvass feature has missing database entries going back 20 years.

I don't see any open or closed issues about it, and a quick poll on Gitter showed no one was using it.

@respencer As a fast follow, can you go through the wiki and remove the references to the canvass feature?

I'm part way through totally redoing the wiki, I just haven't pushed anything yet.

Will add this to my todo list for the wiki.

Awesome! I'm planning on merging this once the tests are done, so we should remove this soon after to avoid having documentation for a nonexistent feature

You need to update the https://github.com/ChurchCRM/CRM/blob/025dbc9d2d9e9ad567ef0bca5ea5461c39273b03/src/mysql/upgrade.json#L372 to support 5.9.0 (I think we yet to move the version of the software) and also the demo/ChurchCRM-Database.sql
