Update deprecated doc for module_exists() and call method inside

Will be done today during Code Sprint UA.

tagging

Attached file with changed doc for function. Also I have changed call method inside this function.

But I think the best way to delete this function from drupal 8 and use Drupal::moduleHandler()->moduleExists('module'); to check exist module or not.
If someone agree with me, I will prepare patch for this.

#7 looks good
if bot`ll happy - RTBC

Don't we want to update this, not delete it?

Too far indented.

Attached corrected patch.

Thanks!
