[JENKINS-26271] Building a git tag doesn't work with multiple remotes

In the git plugin, when multiple repository URLs are configured (note: two remotes, not MultiSCM), building a git tag does not find the correct commit.

Steps to reproduce:

1. Create a job with two git repository URLs (note: two remotes, not MultiSCM). Ensure you name give the second one a different remote name. For example:

   origin -> git://github.com/blt04/jenkins-test1.git
   
   upstream -> git://github.com/blt04/jenkins-test2.git
   
   



2. Run a build using master


3. Configure the branch to be a tag: "test2-1.0"


4. Run the job

Expected results:

Builds the tag

Actual results:

Builds the last built revision
