Function shouldRemoveLocal

s.fileIndex needs to be locked before this function is called A file is only deleted if the following conditions are met: - The file name is present in the d.config.fileMap map - The file did not change in terms of size and mtime in the d.config.fileMap since we started the collecting changes proces
