tests: rework test parameters

there were 2 variants of calling getTestParameter:

    - parameter, description, default value
    - parameter, env value, default value, description, scope

While scope was never actually used and having 2 names for the same value led
to having 2 different entries in the cache file for the same configuration.

This commit removes the variants and simplifies tests parameters by only using
the first 3 parameter variant.
