tests: improve the widening testing in test-narrow-widen*

Before this patch, we are testing `hg tracked --addinclude` by adding a command
which is not introduced in the changesets till now.

If you closely look at the tests, wider/f was introduced on the server after the
narrow clone was done and extending the existing clone to include wider/f does
not make sense. We should test extending a file which exists.

Differential Revision: https://phab.mercurial-scm.org/D4452

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
