Haul flags get removed without hauling complete

[mlinky]

Issue summary

If a haul flag is placed on an abandoned terminal or storage it gets removed before the available resources are removed.

Description of issue:

If a haul flag is placed on an abandoned terminal or storage it gets removed before the available resources are removed.

Steps to reproduce:

Place a haul flag on an abandoned terminal and wait a while, the flag will be removed

Error message:

n/a

// Offending line:

	if (_.sum(this.store) == 0 && this.pos.isVisible) {
		this.remove();			
	}

Suggested fix (optional):

This makes it behave differently, but this has stopped the flag being removed for me

	if (this.totalResources == 0) {
		log.info(`Removing ${this.name} - resources exhausted.`);
		this.remove();
	}
