[test goal] do not display details of errors

[redfish4ktc]

On error/failure, standard maven-soapui-plugin displays the details of the error, for instance, the request, the response, some logs.
This is very annoying when several tests fails: the console is flooded with those useless messages.
We already have the printReport parameter to get a summary of test execution and report files are also generated to know error causes .

So, remove these error details.

Implementation information
The underlying runner (standard and pro implementation) throws an Exception when there are errors. The message of this exception is composed of details describe in the issue.
This exception is catched by the plugin and as for all exceptions, it is wrapped in a MojoFailureException and then, the full useless message is displayed.

Possible solution
The runner does not throw exception when the "ignoreError" is set to true.
So we could use this and ask the runner if there are errors or get the number of errors at the end of the run (should use reflection to access to error list)

The error message is also displayed twice (the exception message is first logged and then displayed again because maven find a MojoFailureException)

        catch (Exception e) {
            getLog().error(e.toString());
            throw new MojoFailureException(this, "SoapUI Test(s) failed", e.getMessage());
        }
