Failure count in report portal is not reflected properly for some cases

[sse2ebdd]

Steps to reproduce -

1. Create feature file with below content and run it with report portal

   
   Feature: Test

@StepDef Scenario: I define something And something_is_true is defined by javascript "false"

@StepDef Scenario: I check whether something is true And I define something until something_is_true

Scenario: Test And step1 is "step1" And I check whether something is true And step3 is "step3" And step4 is "step4" And step5 is "step5"

2. When using GWEN 3.1.2, in report portal failure count shows blank, which should be 1.

3. I tried to compare junit report generated for GWEN 3.1.2 with GWEN 2.54.1. I found below differences.

 - Extra parameter in <testsuite> tag
GWEN 2.54.1 --> tests="1" errors="1" skipped="0"
GWEN 3.1.2 --> tests="1" errors="1" failures="0" skipped="0"

 - Type of error is also different
GWEN 2.54.1 --> error type="gwen.Errors$StepFailure"
GWEN 3.1.2 --> error type="gwen.core.Errors$StepException"

 - There is "system-err" tag present in GWEN 3.1.2 junit report, which is not present in GWEN 2.54.1.

Env -
GWEN version - 3.1.2
Chrome driver - Latest
