Bug fixes and minor updates

- Removed echo from Support Debug dumpVar call
- deprecated DB\IO toggle dbDebug and changed set/get to be like normal
  ones where set just sets and doesn't return anything
- Renamed the logJsDebug to loggingLevelIsDebug
  (other levels can be checked with ->getLoggingLevel()->includes(Level::...))

Adjusted tests for all changes
