Issue:
Possible error in plugin loading logic, says Succeed and Fail for @semantic-release/github
## Current behavior

See logs for Travis CI.  It loads the plugin and then says "Succeed" _and_ "Fail" which shouldn't both be possible.

## Expected behavior

Should just print "Succeed" message.

## Environment

- **semantic-release** version: Latest? Used `npx semantic-release`
- CI environment: TravisCI
- Plugins used: None, defaults?
- **semantic-release** configuration: 
- CI logs: https://travis-ci.org/Microsoft/ConversationLearner-SDK/builds/388041180


Pull request description:
fix(plugin-load): clarify load message
added quotes around plugin name to set it apart from the message. without the quotes, some consumers
were missunderstanding the successful loading of the `fail` plugin as a load failure and assuming
something was broken

resolves #811
