Tag.value is undefined after writing to PLC

[jhenson29]

After writing a tag to the PLC, tag.value becomes undefined.

Current Behavior

Tag value get set to undefined instead of the value it had been set to.

Expected Behavior

Tag value should remain what it was set to.

Possible Solution (Optional)

tag.unstageWriteRequest references this.state.controllerValue instead of this.state.tag.controllerValue This is the source of the undefined value.

Context

Steps to Reproduce (for bugs only)

1. plc.writeTag(tag);
2. console.log(tag.value)

Your Environment

• Package version (Use npm list - e.g. 1.0.6):
• Node Version (Use node --version - e.g. 9.8.0):
• Operating System and version:
• Controller Type (eg 1756-L83E/B):
• Controller Firmware (eg 30.11):

This still isn't right. I was doing more testing in response to the reports of tag writing issues. I fixed the tag.controllerValue reference in #37 but, I think there is another problem. tag.controllerValue isn't getting set so tag.value is just getting put set back to it's last read value. I think the assignment is backwards. I think maybe tag.controllerValue should be getting set to tag.value in the unstageWriteRequest method.
