Select proper flavor_ref_alt for Tempest

Browse Source 
Currently if user selects the default instance type for Tempest
tests, some of resize-related tests may fail due to resize attempt
into flavor with smaller disk size. It is because there is just
simple check if flavor_ref and flavor_ref_alt (IDs) aren't the same.
To ensure resize is really possible, there shall be additional
verification introduced.
