[FIX] make file moving function more robust and fail more gracefully

[Remi-Gau]

This should address #177

• copyGraphWindowOutput will throw warning if it finds no file or more than one file to copy and will throw a warning in those cases but it won't crash.

@CerenB Can you check if this branch solves your issues.

nice, I'll run it today!

@Remi-Gau it is running and falling gracefully for sure.

On a side note, if I run more than one participant at the same time, then the figures for each participant is less than the run number. E.g. First subject has 9 figures, second subject has 8, third one has 6 .png files, and for the last subject it was 3 .png files (total is 9 == total run number).

another not so important issue is with parallel processing, the pipeline does not produce figures. And indeed it's nice that it does not crash, just reports back saying it could not copy any figures because there was none.
