Macromapping of velocity macros when there's no Velocity macro page defined fail and instead include the WebHome page of the current space

In other words, if:

• you're using a velocity macro defined in macros.txt
• you're using the radeox syntax for that macro (eg {yahoo}

  )

• you don't have a velocity macro page defined in the Advanced tab of the Administration page

Then XWiki includes the WebHome page of the current space after the macro...
