alias: make shadowing behavior more consistent (issue2054)

Currently, given an alias like the following:

    [alias]
    summary = summary --remote

The alias might be executed - or it might not - depending on the order
of the cmdtable dict.

This happens because cmdalias gets assigned back to the cmdtable like so:

    cmdtable['summary'] = ...

Yet '^summary|sum' is still in the table, so which one cmdutil.findcmd()
chooses isn't deterministic.

This patch makes cmdalias assign back to '^summary|sum'. It uses the same
cmdtable key lookup that extensions.wrapcommand() does.
