exchange: drop unused '_getbookmarks' function

The function was introduced in 8491845a75b2 in mid-November 2016 but is never
used anywhere in core.

"""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."""
