SERVER-39149 Homogenize getMore behavior
Cursor's have subtly different semantics across mongos and mongod and
between legacy getMore and command getMore. (as does the find command)
Ensuring that all getMores can be paused by
waitAfterPinningCursorBeforeGetMoreBatch, and that cursors are cleaned
up if they are killed after verifying auth, makes testing a bit simpler
and cursors less leaky
And adding a check for waitInFindBeforeMakingBatch to runQuery similarly
makes it easier to test
