Jasmine Adapter clean equality testers added in global scope

[volodymyr-mykhailyk]

Jasmine have ability to add custom equality testers. However when these testers added in global scope (e.g not during actual test run) using following syntax:

jasmine.getEnv().addEqualityTester(MyEqualityTester);

they will be cleaned by jasmine adapter. Reason is that adapter recreate environment before all test are executed in the JSTD register function:

jstestdriver.pluginRegistrar.register({

name: 'jasmine',

runTestConfiguration: function(config, onTestDone, onComplete){
    if (config.getTestCaseInfo().getType() != JASMINE_TYPE) return false;
    (jasmine.currentEnv_ = new Env(onTestDone, onComplete)).execute();
    return true;
},

onTestsFinish: function(){
    jasmine.currentEnv_ = null;
    collectMode = true;
}

});

line:

(jasmine.currentEnv_ = new Env(onTestDone, onComplete)).execute();

In order to fix this adapter should extend already instantiated environment instead of creating new.
