Fix command handler to look up cookieStoreId per command type

Address bakulf's review: each command (open_container/reopen_in_container)
now looks up its own cookieStoreId from identityState.keyboardShortcut
instead of sharing the open_container key's value. Also use shorthand
property in reopenInContainer and fix indentation/semicolon.
