Don't select entity on raycaster click if we used one of the controls take 2

Better fix for #645, revert #709
With further testing while backporting it to aframe-inspector, I still reproduced the issue sometimes when just waiting long enough after moving the mouse and release the mouse button. Actually the fix is simpler, I just used the exact condition as the three.js editor, just compare if mouse distance is zero to do the select entity, that's it.
