rHG0e48813cc106: alias: test duplicated definition earlier
Summary

This patch moves the old definition checking logic introduced by
f4b7be3f8430 earlier. So that the test itself does not depend on aliasdef.

The check is to avoid wrapping a same alias multiple times. It can be done
by checking the config name and value (definition in code), without
constructing a cmdalias instance.

This makes the next patch easier to review.
