Non-ascii chars in EXIF

[villanueval]

Need to allow for non-ascii characters in the EXIF metadata. Or allow for a better error handling when writing the log:

UnicodeEncodeError: 'ascii' codec can't encode character '\\u2013' in position 151: ordinal not in range(128)
File "/var/www/app/osprey_api.py", line 657, in api_update_project_details
  res = query_database_insert(query, row_data)
File "/var/www/app/osprey_api.py", line 86, in query_database_insert
  logger.info("parameters: {}".format(parameters))
