Subject: [PATCH] If a script cannot be found, don't try to run it.

In GhidraScriptComponentProvider.runScript(), if doGetScriptInstance() fails, it writes a diagnostic to the console and returns null.  Proceeding to call doRunScript() with this null will result in a null pointer reference, so if doGetScriptInstance() returns null, just cut things off there.
