Oleksandr Hrabar b7ed99426b fix: Make test suite names match the directory name (#5597) 
This change fixes the suite names all around the test files, to make them match to the folder name in which this test files are located. Also, the RCL test files are relocated to the consensus folder, because they are testing consensus functionality.
