Add missing name field to Pipelines struct

[ppeble]

This is used in the following functions:

• GetPipeline
• GetLatestPipeline
• CreatePipeline
• RetryPipelineBuild
• CancelPipelineBuild

GetPipeline and GetLatestPipeline return the name but the Create, Retry, and Cancel do not. But this will behave the same as DetailedStatus does and just not be set if it's not returned.

API docs for pipelines: https://docs.gitlab.com/ee/api/pipelines.html

This also fixes a go fmt thing? I just followed the contributing guide and ran it and it produced this. 😄
