clearTarget / render sets _currentRenderTarget permanently

[modjke]

Description of the problem

WebGLRenderer clearTarget() or render() with target specified permanently sets current rendering so calling clear() after (or clearColor/Depth/Stencil) clears previous renderTarget and not screen. Calling setRenderTarget(null) before clear() call fixes it.

Sounds like an easy to fix bug. Would you like to do a PR?

clear() ... clears previous renderTarget and not screen.

It is more accurate to say clear() clears the current render target.

If you want to clear a target different from the current one, you have to set the desired target first.
