Fix broken unit test

This unit test worked in 2.4-* branches but not 2.5+. Newer versions of Pulp do
additional parsing of the output of parse_treeinfo and require a mock with more
verisimilitude.
Set the version to 2.4.3-1.
Automatic commit of package [pulp-rpm] release [2.4.3-1].
Merge branch '2.4-dev' into 2.5-testing
