Accept whole action name in the try command (#2691)

When I was trying out the `try` command I hit the similar issue as
described in #2564, as not being able to see the highlighted letter,
I typed out the whole action name which got denied.

Adding support for using whole action name in addition to the shortcut
as it is relatively common e.g., interactive git rebase.
