Details:

This is a spin-off from bug #46944 (patch #9264 comment 2
<https://savannah.gnu.org/patch/?9264#comment2>).

While I was writing automated tests for bug #46944, I found that Flash
Player's implementation of `MovieClip.getURL()`-based FSCommand passes the
`undefined` command parameter to host container as empty string, no matter of
SWF version running.

Gnash, on the other hand, passes it as a string "undefined"; which is
incorrect.

Note: This behavior might not be consistent between `MovieClip.getURL()`-based
FSCommand and normal `getURL()`-based FSCommand, so additional tests would
have to be conducted to clarify the issue (possibly with multiple version of
Flash Player).

Gnash: 0.8.11dev (git 144e082 22-Feb-2017)
Adobe Flash Player: 11.2.202.491 (NPAPI binary)
Browser: Iceweasel 10.0.12 (debian)
System: Debian GNU/Linux 7.0 Wheezy i386

P.S: Automated tests tracking this problem in `MovieClip.getURL()`-based
FSCommand are:
