removed "resolveActivity" check on open camera

[tobiasjungmann]

Issue

This PR is a fix for a small bug I stumbled on. Since I found a solution rather quickly, I've skipped the creating an additional issue.

The problem was that the camera view in the feedback activity could not be opened.

Solution

This code (FeedbackPresenter) finished the method too early:

if (takePictureIntent.resolveActivity(context.packageManager) == null) {  
    return  
}

This check returns null even if successful in more recent API versions. This check is now removed and the potential exception will be caught if the activity does actually not exist.

How to test

Open Feedback tab and add a new image with the camera. Camera view should open.

I will review this once my exams are done next week.
