Summaries should handle correctly UtExecution generated by Fuzzer

[amandelpie]

Description

I propose to make unified handling for all tests, generated by Fuzzer and others

Expected behavior

We should make clusterization for Fuzzing tests too and have the same names for Fuzzer and other produced by summarization framework

Below you could see that cluster for tests generated by Fuzzer is empty.

Probably, we need some flags to differ tests generated by Fuzzer or by Symbolic Executor
Now we are in assumption, that Fuzzer generates UtExecution with path==0, but it could be changed in future

Should think how to cluster error/exception execution found by fuzzer or just error executions - looks like it should be moved to the cluster of error suite (see #823)
