Previously, even if $version were passed to apt::force, aptitude would just
install the default version of the package available. This updates the aptitude
call to use the version string if it exists. If no version is passed, or if it
is false, no version is added to the aptitude call. This also updates the
rspec-puppet tests for the define, to reflect the changes to the exec.
In the Previous commits, the query being done by the
apt::force install command was not strict enough and
could lead to false positives.
These queries represented by the unless parameter have been
resolved in another commit. This commit accompanies that commit
and adds basic unit tests to correspond to the changes.
This commit adds test coverage for apt::ppa.
This test coverage is suficient to verify the
code changes that resolve the issue with
aptitude update not being called when ppas were
added (#10451).
