Top-level (no target) IfTask doesn't work correctly

[hans]

The IfTask is prematurely configured when it is not contained within a target.

Simple reproduction:

<project name="test" default="main" basedir=".">

  <available file="./build.properties" property="globalBuildPopertiesExists"/>
  
  <if> 
  	<and>
  		<isset property="globalBuildPopertiesExists"/>
  	</and>
  	<then>
  		<echo>Yeah, the property was set!</echo>
	</then>	
  </if>
  
  <target name="main">
  	<echo>In main...</echo>
  </target>
  
</project>

The above will always echo "Yeah, the property was set!" regardless of whether the property was actually set.
