[TASK] Fix unittests for isototest #5
Description

Impacted library
isototest
Proposal
Currently the unit test of Isototest are broken, as they never seem to finish.
This may stem from a bad implementation of the start_mock_vnc_srv or mock_vnc_handshake functions in the common.rs module in which some task may not be awaited correctly.
This needs to be fixed before any release can take place.
