Fix coverage with mixed objc swift project

[Branlute]

Fix for issue #50 on sonar-swift

Same Pull Request is open on sonar-swift Idean/sonar-swift#88

Change pattern for coverage.xml for avoid conflicts when upload to SonarQube coverage with both plugins Objective-c and swift.

Hi @Branlute,

I dont think it is necessary to rename the coverage report even when using both languages. I think the coverage report is global for the project and not language dependent (but I'm not sure).

Do you have a special case that lead you to do that ?

Hi @zippy1978 ,

You are right, the coverage report is global, but if SonarQube has both Objective-C and Swift plugins installed, both plugins will try to upload coverage to SonarQube, and SonarQube will only accept one report. So you will have an error.

With this fix, the Objective-c plugin will not upload the coverage generated by swift's script "run-sonar.sh" and vice versa.
