log csv error if running C-PAC for a second time with same working dir

[XinhuiLi]

Since C-PAC 1.6.2, users and I have observed an error caused by csv file in log folder if C-PAC was run for a second time based on same working dir. This issue is probably due to py3 upgrade and one of temporary solutions is to remove previous log folder. However, running C-PAC multiple times with same working dir should be handled gracefully.

Traceback (most recent call last):
File "/code/CPAC/pipeline/cpac_pipeline.py", line 539, in run_workflow
for line in timeReader:
File "/usr/local/miniconda/lib/python3.7/csv.py", line 111, in next
self.fieldnames
File "/usr/local/miniconda/lib/python3.7/csv.py", line 98, in fieldnames
self._fieldnames = next(self.reader)
_csv.Error: iterator should return strings, not bytes (did you open the file in text mode?)

What is the CSV file? It might be deprecated anyway.

The CSV is cpac_individual_timing_{c.pipelineName}.csv in log folder.
