Fix broken suggestions

Closes #72 (closed)

• runData was not updated before, now we always use the latest available runData for determining suggestions
• renderSuggestions was the wrong function to give to watchdir, as it does not actually update the watched modules but only uses them. To fix this introduced a function that updates the (global) loadedModules
• In the suggestions for failing processes during a run a typo was present in the arguments to the exported functions
• Furthermore the subsystems list returned by the runInfo contains subsystems that are not in the list of monitored subsystems (ECAL, HCAL, DT, RPC and CSC) so a check has been put into place before trying to access the apps and looping over the apps has been fixed as well
