Fix the issue https://github.com/CocaineCong/tangseng/issues/48 .I change the files in ./pkg and ./repository. Use "github.com/pkg/errors" to wrap error. In a word, If a function doesn't need to return an error, print the error and stack information with logrus, otherwise wrap the error and append some information.
