[BUG] componentSetEffect passes null in Generic Component RGBW Light Effects

[gslender]

The Generic Component RGBW Light Effects device passes a null effectnumber to the parent driver when the setEffect command is executed with any value.

The following code snippet produces the below log output

void componentSetEffect(cd, effectnumber) {
  log.debug "componentSetEffect effectnumber=$effectnumber"} 
}

componentSetEffect effectnumber=null

There is also a spelling bug in the same child driver...

componentSetPrevoiusEffect is called instead of componentSetPreviousEffect

[mike.maxwell]

both of these will be fixed in a forth coming 2.2.8 hot fix

Think I found another bug in the same component... setLevel logs to debug as null even though the level is sent to the Parent correctly - might be worth fixing that too
