Christian Decker c9d24b1de2 pyln: Set the prefix in TailableProc
We rely on it when logging, but didn't set it in the class, rather we
did in the sub-classes. This proved to be rather annoying to search
since it'd just fail silently and not log any output.

Rusty Russell e4950db9a3 pytest: recreate wallet on bitcoind restart.
Doesn't seem to stick in master.  Andy Chow suggested we
simply turn off wallet on older versions, and always create/load.

establish a floor for this case.
