fix watch wakeup test

[kostmo]

This improves the test introduced in #1736 in a few ways:

• Place the system robot's code inline in the program field
  • even though the system bot had been using instant, the run command itself incurs a delay. So this ensures the system robot is ready to monitor the cell immediately
• System robot uses exclusively Intangible commands in its monitoring loop
  • This allows removal of the instant command.
  • Surveil, which does not appear in any scenario yet, is made Intangible.
• Remove the initial wait 2 in the player robot's solution.

Tested to ensure that this still exercises the problem that #1736 set out to solve, by commenting out this line (causing the scenario to fail).

Makes sense to me.
