Issue Description

PublishCodeCoverageResults@2 fails to publish the coverage report when there are more than 1800 files in it. I don't have a hard number, but I have builds with ~500 files in the report that work properly and builds with 1800+ that get 60+% of the way through uploading the files and then just stop without any errors.
