D487: test-extension: enable demandimport explicitly

[quark (Jun Wu)]

quark added a comment.


  I disabled demandimport because it had caused subtle issues for me in the past. Now chg also disables demandimport. Maybe the correct fix is to replace the stack trace matching to be not depend on demandimport.
