fix error of non-found smach_tutorials.msg

[LongfeiProjects]

import smach_tutorials.msg would cause an error. A quick fix applied to eliminate this error.

@LongfeiProjects FYI I'm suggesting to move executive_smach_tutorials to ros organization in ros/common_tutorials#19

I don't see which kind of error you get. In any case, the fix doesn't make sense to me. You load the msg of a completely different package now...
Also note, that this repo is a private fork and I'm not the maintainer of this package. I'm not sure who is...

I found the following error while I run both actionlib examples (actionlib_test.py and actionlib2_test.py) under folder executive_smach_tutorials/examples. The error messages are below:

Traceback (most recent call last):
File "./actionlib_test.py", line 25, in
from smach_tutorials.msg import TestAction, TestGoal
ImportError: No module named smach_tutorials.msg

When I check further about this problem, I didn't found that "smach_tutorials.msg" in this tutorial repository. Therefore, this error make sense. However, I found "TestAction" and "TestGoal" are actually from built-in ROS "actionlib.msg". I made the change and everything pass.

I totally understand this is a private fork. I tried to find the source, but the most original source I could find is "https://code.ros.org/svn/ros-pkg/stacks/executive_smach_tutorials/trunk", which I could not open. I was thinking all the rest were forks and some of them had no activity for few years. Then I made this issue for discussion on a most recent updated fork, looking for a fast response.

I might be wrong in somewhere, and any comment is welcome.

@130s Is there anything I should do to gracefully relocate/migrate the issue to "ros/common_tutorials"? Or should I wait the comment/confirmation of the issue from other experts first?

@LongfeiProjects I'm not yet sure if ros/common_tutorials#19 gets merged. If not, though, I'll open another PR to somewhere appropriate and close to ROS core pkgs.

For now, you can open a PR against my fork, which I use for ros/common_tutorials#19.
