[PATCH (GITK)] gitk: Avoid handling the Return key twice in Add Branch.

This reverts commit 63767d5fb8fe236d8fdeba44297ac925701b27a0.

A similar change was made as part of commit 76f15947af7,
that added bindings to all dialogs, and this duplication
causes mkbrgo to be called twice, the second time after
the window has been destroyed. As a result, an error
window appears when the code tries to access widgets.
