[test] ensure rev system works in shared db

During a meeting with pixelated we were asked to ensure that the u1db
revision system was working for the shared database. This commit adds a
test to make sure that documents in the shared database can be updated
successfully if the include the correct revision, but will fail if the
include the incorrect revision.

Resolves: #8842.
