Introduced by an optimisation :tm: in
https://github.com/ShiftLeftSecurity/overflowdb/pull/180, removing
a node would result in setting nodesList = null. Not all places that
accessed nodesList checked for that, resulting in
a NullPointerException. That's fixed now.
Also fixes a race condition, e.g. triggered by "one thread removes a node and
a different thread gets the nodes". The fix only works with a separate
reference and doesn't add extra synchronized blocks.
