Suricata

Currently, if one wants to run Suricata-verify for a specific test, but inadvertently makes a typo in the name, the program runs and shows results that don't make it clear that it didn't find any test with the given name:

This can be misleading and time-consuming, as especially newcomers could interpret this as having something wrong in the code they are trying to test, somehow, instead of it being a possible issue with test name.

[Expected behavior:]
A simple Warn message informing the user that `provided test name` didn't match any test candidates should be enough.
