revset: add test that should fail if '_aliasarg' tag is removed

I'm going to refactor the alias processing functions. We need '_aliasarg' tag
to limit the scope of the alias expansion, but it wasn't covered by the test.
This patch adds the test that should fail if '_aliasarg' were 'symbol'.

This is the first half of the second part of the "template alias" series. The
whole series will consist of the following parts:

 1. make parsed template tree to be compatible with parser functions
    (1d461ee26e1b and 73d01cba5810)
 2. refactor alias processing to be less dependent on revset module
    (1/2 in this series)
 3. extract reusable component to parser module
 4. clean up it
 5. extend it to support template syntax
 6. add debugging/testing functions of template aliases
 7. add alias expansion routine to templater

"""test behavior of propertycache and unfiltered propertycache

The repoview overlay is quite complex. We test the behavior of
property cache of both localrepo and repoview to prevent
regression."""
