We have that call in step 5 here: https://github.com/bitcoin/bitcoin/blob/master/src/init.cpp#L609
and again in step 7: https://github.com/bitcoin/bitcoin/blob/master/src/init.cpp#L745
It seems like a duplicate block of code and even we check for if (fDbEnvInit) in .Open(), I'm asking if that could be removed because we don't need it.
