Sound_play node becomes invalid after running for a while

[itohdak]

There has been an issue that sound_play node becomes invalid after running for a while.
I found two following causes for this issue.

• error in gstreamer among sound_play node.
• error in rosservice call among text2wave in this package.

This issue aims the latter.
I found that the rosservice call correctly printed the response but didn’t exit and kept holding the control, just before sound_play node for Japanese became stuck.
I think this issue relates with this.

Instead of debugging the rosservice call source, I tried to call the service through Python node, not through bash command in #166.

Are there any other solutions for this issue?

I have applied and tested the PR with the robot for some months, not facing the problem for now on.
