create_standardized_filename matches multiple files

Created by: williamschmitt21

create_standardized_filename can match multiple files when using the auto-number increment feature because the description search is non-exhaustive. That is, if there is a file RXX-sample_description-YYY_MM_DD-vX.X.X.csv and RXX-sample-YYY_MM_DD-vX.X.X.csv, and one attempts to provide a description of sample it will return both of these filenames.

Solution: constrict the matching_description variable to match a string that has -description- instead of just description.
