The webform_remote_post git repository has two unneeded branches and the latest tag, 7.x-1.2, is not on branch 7.x-1.x. These git commands will fix things up:

Include 7.x-1.2 in 7.x-1.x:
git checkout 7.x-1.x
git merge 7.x-1.2
git push origin 7.x-1.x

Delete unneeded branches:
git push origin :7.x-1.2-alpha1
git push origin :field-injection
