Redundant Mocha Reporter Node <div id="mocha"></div>

[chrisbottin]

Hi,

I've noticed the node <div id="mocha"></div> is created by this plugin whenever I'm running karma in debug mode and the mocha reporter is set to "spec".

This node is only used by the mocha HTML reporter so ...

Should this code

karma-mocha/src/adapter.js

Lines 122 to 125 in bb5be9b

	if (isDebugPage && haveMochaConfig(tc) && tc.config.mocha.reporter) {
	createMochaReporterNode()
	return tc.config.mocha.reporter
	}

be changed to check which reporter is used like this?

if (isDebugPage && haveMochaConfig(tc) && tc.config.mocha.reporter === 'html') {
    createMochaReporterNode()
    return tc.config.mocha.reporter
}

btw, happy to create a PR for it if the changes are sound.
