BF: Find and save orphaned data at end of online task

[dvbridges]

This fix solves a problem where routine data was not saved
if no loops came after that routine (because nextEntry was not called).

This current implementation will not work until PsychoJS
Experiment Handler attributes of _trialsData and thisCurrentTrial
are changed to entries and thisEntry, respectively.

@peircej , another situation has arisen where data not being saved. In a nested loop, with the outerloop isTrials is False, and the inner loop isTrials is True, a participant ending their inner loop on the first iteration, but repeats inner loop n times based on number of trials in the outerloop, will not have data saved. This is because breaking the inner loop on the first iteration does not call nextExtry(), and the outer loop where isTrials is False does not call nextEntry(). Calling at the end of the task will only write the last trial recorded. The solution is to call nextEntry in endLoopIteration() when currentLoop is true.
