fix: stop error when tool has no instructions (#493)

Previously, if a tool had no instructions, then the SDK would report an
error because there would have been no output. That has been changed in
the SDK.

Now, in these changes, if a blank message is received when running a
tool, a special "no response received" message will be displayed to the
user.
