Use `ctest` or `make test` to run all tests.
With this it's also possible to run tests on a Mac.
Relative paths used in tests become absolute ones to make tests
executable from any build folder.
Also fixed race condition in
test/broker/11-persistent-subscription-no-local.py

This change in behaviour can be justified by considering when the
timeout may have occurred.
* If a connection is unreliable and has dropped, but without one end
noticing, the messages will be retried on reconnection. Sending
additional PUBLISH or PUBREL would not have changed anything.
* If a client is overloaded/unable to respond/has a slow connection then
sending additional PUBLISH or PUBREL would not help the client catch
up. Once the backlog has cleared the client will respond. If it is not
able to catch up, sending additional duplicates would not help either.
