Functional tests running on develop branch don't report failure

[igor-sirotin]

Here's a PR job, properly failing: https://ci.status.im/blue/organizations/jenkins/status-go%2Fprs%2Ftests-rpc/detail/PR-5969/15/pipeline/

And here is the job for develop branch getting same error, but passing:

https://ci.status.im/blue/organizations/jenkins/status-go%2Ftests-rpc-develop/detail/tests-rpc-develop/7/pipeline/

---

So it looks like all jobs are passing. But in fact all of them have failed 🙁

The issues that lead to failure are fixed here:

• fix_: functional tests #5979

I would make a branch from failing commit, add sebug to the _assets/scripts/run_functional_tests.sh.

Actually, the error .../bindata.go": no such file or directory is coming from the go tool covdata command. That's why it doesn't affect the final exit code. Not sure if it should.
The actual bug of not generating files was fixed here: #5979
