manifest: use rev() instead of nodemap.__contains__

nodemap is an implementation detail of revlogs and isn't
appropriate to expose on the manifest storage API.

While revlogs don't have a __contains__, they do have lookup()
for resolving a value to a node. And this calls rev(), whose API
is documented to raise LookupError if a node doesn't exist. And
the parameters to LookupError are identical to what was being
raised here. So this change should be backwards compatible.
