repo start should not need a project name if the branch is unique

When I try to start a branch that already exists, repo still asks me to supply
the project name, which seems unnecessary if that branch name is unique:

$ repo branches
   CommentReplies            | in gerrit
*  Debug                     | in gwtexpui
   InlineImages              | in gerrit
*P InlineImagesCherryPick    | in gerrit
 P SearchByUser              | in gerrit
   master                    | in gerrit
   save                      | in gerrit

$ repo start SearchByUser
error: at least one project must be specified

Couldn't repo determine that the project is `gerrit` since it's the only one
that contains a branch called SearchByUser?
