Updating relations prop about react-archer HOT 8 CLOSED

Thanks @robinvenneman for handling this.
I'll have to dive into this and think this through as well. Sorry about all these issues 😄

As always, your PR is very welcome 😊

So indeed there is a mistake in the relationsWithStringifiedLabels, it only compares labels right now (which was not intended).

But even fixing it raises another issue: when you change a relation from one arrow to point to another element, the previous relation is not removed.

I have a solution for this, I'll try to implement it asap!

@AlisonWonderlandApps Yeah I've fixed dynamically adding / removing elements and adding or removing relations by updating the props... I will open a PR soon, just haven't completely figured out that relationsWithStringifiedLabels check yet.

This PR #25 should solve it 😊

@robinvenneman & @pierpo I'm having this same issue... did you have a workaround on forcing the arrows to re-render once they get a new relation? (code snippet would be great!)
My issue is that I have several different graphs to display in different tabs, but the arrows only render correctly for the FIRST display.
I also cannot manually draw arrows between 2 nodes by adding a new relation to the graph once already rendered :(
Any suggestions or help would be appreciated!!!

Great job @pierpo thanks! A bit different from my solution but it works perfectly.
