one failure;

=== RUN   TestNetworkDBCRUDTableEntries
2020/02/26 21:17:43 Closing DB instances...
--- FAIL: TestNetworkDBCRUDTableEntries (7.61s)
    networkdb_test.go:141: Entry existence verification test failed for node2(9dab403365ae)

failure above is difficult to locate, because the error occurs in a helper that's used in many tests. Pushing a commit to mark helper-functions as t.Helper() to see if the output is more usable

[thaJeztah]

.....and now it passes of course, LOL. Looks like it's just a flaky test

[thaJeztah]

Rebased this PR, and had the same failure as above, so could be related

[thaJeztah]

nope; passes again now, so looks to be just flaky
