XML substitutions are not replaced when building an xAPI course from the Adapt Authoring Tool

[mediabounds]

The tincan.xml file in the courses we export from the Adapt Authoring Tool (v0.2.2) with Adapt Framework 2.0.15 do not have the placeholders replaced:

<?xml version="1.0" encoding="utf-8" ?>
<tincan xmlns="http://projecttincan.com/tincan.xsd">
	<activities>
		<activity id="@@config._xapi._activityID" type="http://adlnet.gov/expapi">
			<name>@@course.title</name>
			<description lang="en-US">@@course.description</description>
			<launch lang="en-us">index.html</launch>
		</activity>
	</activities>
</tincan>

After further investigation, we determined that this is actually reproducible when just using the grunt build process for the source code of the course. Running

grunt clean && grunt build

yields a tincan.xml file that looks like the one above. However, executing

grunt build

again successfully replaces the placeholders.

It appears that when the replace task is loaded, it immediately goes and searches for the config JSON file, but that file isn't built yet.

Parsing the config JSON needs to be deferred until the replace task executes.
