test-alias: make it compatible with chg

ad1bdea (dispatch: defer environment variable resolution in alias commands
(BC), 2016-05-06) made environment variables lazily resolved. But after
D805 (alias: make alias command lazily resolved 2017-09-23), alias
resolution happened after uisetup, which breaks the test for chg.

`uisetup` is known to behave different in chg. Let's verify the feature
without using `*setup`.
