Notify, if some suite name from general config never used

[kgevorkyan]

If, for example, user will provide some value for suiteName in top level config, but immediately rewrite this value in child configs, thus top-level suiteName will not be used - probably user forget to provide test resources for the top level config or make an mistake, since the suite name without resources have no sense.

In such case we need at least to notify about it.
