Valgrind regression for 3.11.0 + fixes

[fgalan]

This PR will be closed without merge after use. At the end some fix was included, so the PR was actually merged.

Similar to PR #4370

The only test that fails seems to be a glitch, as local execution works fine:

Great, all valgrind tests ran without any memory leakage

Rerunning tests...

It has failed same test in the second attemp

 1 test cases show valgrind errors:
  849: filtering_out_all_metadata_sub shows 4 valgrind errors

I have also checked with the CI image and it works:

docker run --network host --rm -e CB_NO_CACHE=ON -e FT_FROM_IX=849 -e FT_TO_IX=849 -v $(pwd):/opt/fiware-orion telefonicaiot/fiware-orion:ci build -miqts valgrind

Edit:* running also without -e CB_NO_CACHE=ON and goes ok:

Another run in local with CI image with the failing test and some previous ones:

In github attemp number 3:

2 test cases show valgrind errors:
  655: long_service_names_in_subscriptions shows 4 valgrind errors
  849: filtering_out_all_metadata_sub shows 4 valgrind errors

In github attemp 4:

3 test cases show valgrind errors:
  655: long_service_names_in_subscriptions shows 4 valgrind errors
  803: more_than_1000_types shows 31 valgrind errors
  849: filtering_out_all_metadata_sub shows 4 valgrind errors
---------------------------------------

This is getting weird :)

Attemp 5 finally worked. That shows the fail was a glitch.
