List of changes shows only the top commit instead of showing all the commits since last build. This isn't a true reflection of what the build is running with.

Go version: 15.2.0(2248-c1f90a6aa3192a)
OS: macOS Sierra 10.12.3
plugin version: 1.3.1

Reproduce step:

• commit one change to one branch locally
• commit another change to the same branch locally
• push these two changes to remote
  The pipeline triggers but only the last commit is listed in the 'Changes' dropdown.
