metal: Make sure we have a command buffer available before trying to present.

This fixes a case where you render to the backbuffer, then render to a render
target, set the current target back to the backbuffer, and then present
without drawing anything else; in this circumstance, the Present command
would never happen.

Fixes Bugzilla #5011.
