genie_python: reload_current_config doesn't always restart IOCs

If the blockserver has just been restarted and the user runs g.reload_current_config(), then IOCs restart.
However, if the configuration has been saved since restarting the blockserver, then IOCs do not restart.

This is inconsistent behaviour.
Should g.reload_current_config() always restart everything including IOCs, or should it be selective?

The docstring for the function and the wiki should be clear on what the function does and does not do. If the behaviour is wrong, then it needs to be changed.
