__git_flow_list_remote_features was returning remote features with full prefix (origin/feature/) for autocompletion.
This reverts commit 88a4235. Conflicts: git-flow-completion.bash
Use gitflow's feature prefix configuration option when fetching remote feature branches. This is used to determine which remote feature branches are available when completing 'feature track'.
