Reverted setting of local variable $table in saveorder so data can be updated.  Also corrected invocation of createTagsHelper that caused the save to error out on my system[must be $this->createTagsHelper)
Fixed saveorder maintaining tags.

$this->tableClassName and other variables were only set if one of the batchXXX methods in the model were invoked, saveorder does not go through a batchXXX method in the model., causing issues.   Replaced them with local variables and made sure to set/retrieve the data.

$this->typeAlias: as far as I can tell, this parameter is /never/ set in this class.  Replaced with local variable $typeAlias and set it.

Update the call to createTagsHelper to use the local variables that were set.  An added benefit of local variables is that the IDE can now check to ensure that they have been set.
